HBASE-650 Add String versions of get, scanner, put in HTable
HBASE-656 Do not retry exceptions such as unknown scanner or illegal argument
A  src/java/org/apache/hadoop/hbase/ColumnNameParseException.java
A  src/java/org/apache/hadoop/hbase/LeaseException.java
    Added.  Thrown instead of IllegalArgumentExceptions
M  src/java/org/apache/hadoop/hbase/Leases.java

M  src/java/org/apache/hadoop/hbase/HStoreKey.java
    Use new ColumnNameParse in place of IllegalArgument
M  src/java/org/apache/hadoop/hbase/master/ServerManager.java
    Log at debug if LeaseException (Not important if it happens).
A  src/java/org/apache/hadoop/hbase/DoNotRetryIOException.java
    An IOE that shouldn't be retried.
M  src/java/org/apache/hadoop/hbase/InvalidColumnNameException.java
M  src/java/org/apache/hadoop/hbase/UnknownScannerException.java
    Inherit from DoNotRetryIOException else we keep trying.
M  src/java/org/apache/hadoop/hbase/util/Bytes.java
    (toByteArrays): Added one to handle [] String.
M  src/java/org/apache/hadoop/hbase/client/HTable.java
    Make String overrides of all methods.  Made data members
    private (turns out a bunch arent' even used).  Stopped it
    inheriting from HConstants so we don't have big dump of
    all HConstants as first thing in javadoc.
M  src/java/org/apache/hadoop/hbase/client/HConnectionManager.java
    If instance of DoNotRetryIOException, let the exception out.
M  src/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
    Make String overrides of all methods.  Stopped it
    inheriting from HConstants so we don't have big dump of
    all HConstants as first thing in javadoc.

Jim Kellerman 8d5e1e7025 HBASE-624 Master will shut down if number of active region servers is zero even if shutdown was not requested
M HMaster

- Moved HMaster.quiescedMetaServers to ServerManager.quiescedServers and changed name since only servers serving user regions get quiesced.
- Removed HMaster.tableInCreation - not used

M ServerManager

- Don't check if quiescedServers.get() >= serversToServerInfo.size() unless master.shutdownRequested is true.

M HRegionServer

- Change order of checks in main loop of HRegionServer.run, so that booleans are checked before we check the number of messages to process
- Don't break out of main loop if restart or stop requested - stop is checked at top of loop and we need to continue rather than break out of main loop if restart was requested

Jim Kellerman ab778e22e4 HBASE-607 MultiRegionTable.makeMultiRegionTable is not deterministic enough for regression tests
M MultiRegionTable

  Make deterministic by creating the regions directly and not rely on
  the asychronous nature of cache flushes, compactions and splits. The
  regions are small, but the point of this class is to generate a
  table with multiple regions so we can test map / reduce, region
  onlining / offlining, etc.

  Removed PUNCTUATION from row keys. Not sure why it was there in the
  first place, other than perhaps to verify that a row key can have
  punctuation in it provided it is not the first character. This will
  become moot when row keys change from Text to byte[] anyways.

  Incorporate repeated code
{code}
    region.close();
    region.getLog().closeAndDelete();
{code}
  into private method closeRegionAndDeleteLog

M TestSplit

  extends HBaseClusterTestCase instead of MultiRegionTable. It didn't
  use the output of MultiRegionTable, so all that work was just wasted
  by this test.

M TestTableIndex, TestTableMapReduce

  The only two tests that currently use MultiRegionTable. Minor
  modifications needed because MultiRegionTable now handles starting
  and stopping of the mini-DFS cluster. With the new MultiRegionTable
  class, if these tests fail now it will be because something they are
  testing has regressed and not because MultiRegionTable failed.

Michael Stack cffa3a254e HBASE-586 HRegion runs HStore memcache snapshotting -- fix it so only HStore
knows about workings of memcache

HStore knows about workings of memcache

This patch moves the running of mecache snapshots out of the control
of HRegion and hides the memcache details in HStore.   This patch also
does a bunch of work on the merge tool fixing a bug in the metautils along
the way.  The merge tool test was failing.  We weren't setting into the
HLog the maximum sequence id after we'd opened a region -- as HRS does --
so were losing edits. On the way, refactored the merge tool test to get
rid of duplicated code.  Finally, cleans up logging in HStore to aid
debugging; e.g. we always refer to the sequence id as the 'sequence id'
in log messages rather than as seqId or 'sequence record' so can sort
log as see state of sequence id transitions.

Version 2 changes the order in which things are run in memcache.  532
made it so flushing did snapshot and then cleared the snapshot.  Now,
we snapshot before we flush a store, then inside in the store flush,
we call getSnapshot and then clearSnapshot.

M  src/test/org/apache/hadoop/hbase/regionserver/TestHMemcache.java
  How snapshotting changed.  Change test in accordance.
M  src/test/org/apache/hadoop/hbase/regionserver/TestHLog.java
  Use accessor to get file number.
M  src/test/org/apache/hadoop/hbase/util/TestMergeTool.java
  Refactored to remove duplicated code so could tell what was going on.
  (mergeAndVerify, verifyMerge): Addd.
M  src/java/org/apache/hadoop/hbase/regionserver/Memcache.java
  (snapshot): Changed so it no longer returns snapshot.
M  src/java/org/apache/hadoop/hbase/regionserver/HStore.java
  Changed log messages removing the useless and adding info to others.
  (this.maxSeqId): We used to add 1 to this in here in HStore.  Let
  HRegion do it.  Its the one that does the machinations w/ sequenceids
  anyways.  Make flushes return the amount flushed.  Use this updating
  the regions memcacheSize accounting.
  (snapshot): Added method for the region to call.
M  src/java/org/apache/hadoop/hbase/regionserver/HLog.java
  Made data members private.
  (getFileNum): Added accessor for tests.
M  src/java/org/apache/hadoop/hbase/regionserver/HRegion.java
  Added info to logs..
  (snapshotMemcaches): removed.
  (internalFlushcache): No longer takes startime.  Internally now does
  some of what used happen in snapshotMemcaches including sending of
  message to stores to snapshot.
  (getEntrySize): Added method for calculating size of an update. Used
  by HRegion and flushing so both come up w/ same answer.
M  src/java/org/apache/hadoop/hbase/util/Merge.java
  Add logging of whats happening during merges and fail earlier than we
  used if stuff is not right.
  Renamed local variables from region1 to r1, etc., so didn't clash
  with data members of same name.
M  src/java/org/apache/hadoop/hbase/util/MetaUtils.java
  Added a TODO

Jim Kellerman 6e225dd7f1 HBASE-469 Streamline HStore startup and compactions
HMerge, HRegionServer

- changes that reflect changes to HRegion, CompactSplitThread and Flusher methods

ServerManager

- Return zero length array to region server if it is exiting or quiesced and Master is not yet ready to shut down.

QueueEntry

- removed. no longer used.

CompactSplitThread

- make compactionQueue a queue of HRegion.
- Add Set<HRegion> so we can quickly determine if a region is in the queue. BlockingQueue.contains() does a linear scan of the queue.
- Add a lock and interruptPolitely methods so that compactions/splits in progress are not interrupted.
- Don't add a region to the queue if it is already present.

Flusher

- change queue from DelayQueue to BlockingQueue, with HRegion entries instead of QueueEntry.
- Add Set<HRegion> to quickly determine if a region is already in the queue to avoid linear scan of BlockingQueue.contains().
- Only put regions in the queue for optional cache flush if the last time they were flushed is older than now - optionalFlushInterval.
- Only add regions to the queue if it is not already present.

HRegion

- don't request a cache flush if one has already been requested.
- Add setLastFlushTime so flusher can set it once it has queued an optional flush.
- Replace largestHStore with getLargestHStoreSize: returns long instead of HStoreSize object.
- Add midKey as parameter to splitRegion.
- Reorder start of splitRegion so it doesn't do any work before validating parameters.
- Remove needsSplit and compactIfNeeded - no longer needed.
- compactStores now returns midKey if split is needed.
- snapshotMemcaches now sets flushRequested to false and sets lastFlushTime to now.
- update does not request a cache flush if one has already been requested.
- Override equals and hashCode so HRegions can be stored in a HashSet.

HStore

- loadHStoreFiles now computes max sequence id and the initial size of the store.
- Add getter for family.
- internalCacheFlush updates store size, and logs both size of cache flush and resulting map file size (with debug logging enabled).
- Remove needsCompaction and hasReferences - no longer needed.
- compact() returns midKey if store needs to be split.
- compact() does all checking before actually starting a compaction.
- If store size is greater than desiredMaxFileSize, compact returns the midKey for the store regardless of whether a compaction was actually done.
- Added more synchronization in completeCompaction while iterating over storeFiles.
- completeCompaction computes new store size.
- New method checkSplit replaces method size. Returns midKey if store needs to be split and can be split.

HStoreSize

- removed. No longer needed.

HBaseTestCase

- only set fs if it has not already been set by a subclass.

TestTableIndex, TestTableMapReduce

- call FSUtil.deleteFully to clean up cruft left in local fs, by MapReduce

server reports that it is processing the open request

This is patch reviewed with Jim but with the number of edits between
reports made into a configurable.

Have the HRegionServer pass down a Progressable implementation down into
Region and then down int Store where edits are replayed. Call progress
after every couple of thousand edits.

M src/java/org/apache/hadoop/hbase/HStore.java

M src/java/org/apache/hadoop/hbase/HMaster.java

  New constructor that takes a Progressable. Pass it to Stores on construction.
M src/java/org/apache/hadoop/hbase/HRegionServer.java

Bryan Duxbury feb4f2d2b6 HBASE-528 table 'does not exist' when it does
-Changed HStore and Memcache methods for computing closest row at or before
-Added more test cases for verifying this functionality
-Simplified the getClosestRowBefore interface so that it does not take timestamps
-Noted that getClosestRowBefore is assumed to work correctly ONLY on tables where updates are always with ascending timestamps (method is still not a part of HTable interface, so not available to clients)

Michael Stack c1f974bbee HBASE-501 Empty region server address in info:server entry and a startcode of -1 in .META.
M conf/hbase-default.xml
Add hbase.hbasemaster.maxregionopen property.
M src/java/org/apache/hadoop/hbase/HStore.java
Change way we log. Do way less. Just emit sums of edits applied
and skipped rather than individual edits.
M src/java/org/apache/hadoop/hbase/HRegionServer.java
Make sleeper instance a local rather than data member.
(reportForDuty): Take a sleeper instance.
(run): Removed redundant wrap of a 'for' by a 'while'.
(constructor): If IOE, do not offline the region. Seen to be
an overreaction.
M src/java/org/apache/hadoop/hbase/HLog.java
Don't output map of all files being cleaned everytime a new
entry is added; instead just log new entry. Remove emission
of every 10k edits.
M src/java/org/apache/hadoop/hbase/HMaster.java
Up default for maxregionopen. Was seeing that playing edits
could take a long time (mostly because we used log every
edit) but no harm in this being longer. On REPORT_CLOSE,
emit region info, not just region so can see the properties
(W/o, made it hard to figure who was responsible for offlining).
Add logging of attempt # in shutdown processing.
Add logging of state flags passed to the close region. Helps
debugging. Also in close offline ONLY if we are NOT reassigning
the region (jimk find).
M src/java/org/apache/hadoop/hbase/util/Sleeper.java
Add logging of extraordinary sleeps or calculated periods
(suspicion is that we're sleeping way longer on loaded machies
and the regionserver appears hung).

Jim Kellerman 9057e559a1 HBASE-27 hregioninfo cell empty in meta table
Summary of changes:

HMaster:

- When a row has an empty HRegionInfo (info:regioninfo), log it with the row name and and the other keys still in the row.

- Log the number of rows with empty HRegionInfo

- Delete the rows

- Make RowMap inner class static, change methods to have package scope to avoid synthetic accessors.

- Provide row name to getHRegionInfo so it can issue better log messages

- add method deleteEmptyMetaRows to remove rows with empty HRegionInfo

HRegion

- change removeRegionFromMETA to use deleteAll rather than using a BatchUpdate containing deletes for each cell.

TestEmptyMetaInfo

- new test case

HLog

- don't overwrite oldlogfile in splitLog if it already exists. Rename it and copy it into the new oldlogfile. Then delete it once it has been copied.
- use FileUtil.fullyDelete to delete region server log directory.

HRegion

- delete oldlogfile once it has been successfully processed

Jim Kellerman 9a88155bf0 2008/02/04 HBase is now a subproject of Hadoop. The first HBase release as a subproject will be release 0.1.0 which will be equivalent to the version of HBase included in Hadoop 0.16.0. In order to accomplish this, the HBase portion of HBASE-288 (formerly HADOOP-1398) has been backed out. Once 0.1.0 is frozen (depending mostly on changes to infrastructure due to becoming a sub project instead of a contrib project), this patch will re-appear on HBase trunk.

HADOOP-2392, HADOOP-2324:

Chore
- initialChore() now returns boolean

HMaster
- rather than retry in root and meta scanners, return if a scan fails. It will get retried on the next scan. This has two effects: 1) scanners exit more quickly during shutdown and 2) they don't keep retrying to connect to a dead server, allowing them to recover from a server going down more quickly.
- initialScan in root and meta scanners return boolean and do not progress to maintenanceScan until the initial scan completes successfully.

HRegionServer
- speed up region server exit by reordering join's so that we join with threads in the order that we told them to stop

TestTableMapReduce
- remove overrides of heartbeat and thread wake intervals

HADOOP-2396:

HMaster
- move check for null HRegionInfo before first attempt to dereference it.

HADOOP-2397:
- HMaster$BaseScanner.checkAssigned: don't try to split dead server's log if initial startup has completed.

HADOOP-2353:

HMsg
- change toString() to only output the region name rather than calling HRegionInfo.toString()

StaticTestEnvironment
- make logging a bit less verbose

TestHLog
- was writing to local file system and failing on Windows

Jim Kellerman 8a5b3da292 HADOOP-2139 (phase 1) Increase parallelism in region servers
There are a lot of changes in this patch. The memcache has been changed from a per/region object to a per/column object, and HLocking has been removed since we do not have to maintain any locks across RPC calls.

This necessitated major changes to HRegion and HStore

Additionally there were many changes required to the unit tests since they tend to exploit some private interfaces that weren't designed to be public. Some of those interfaces changed so the test cases did as well.

This patch is the result of extensive analysis of the multiple threads in HBase that contend for shared resources: updates, reads, scanners, cache flushing, compaction and region splitting.

Many of the tests are timing sensitive, and since we tend to make "dormant" intervals as short as possible to speed up the Hudson build, we may go through several iterations of getting them right before Hudson is happy. This is especially true since two test cases failed on my dual cpu windows machine while running the tests under Ant, but ran fine under Eclipse.

However, now that the tests are passing locally, I believe the changes are doing the right thing, but may require some parameter tweaks.

Jim Kellerman 8a3bc9c23e HADOOP-1966 Make HBase unit tests more reliable in the Hudson environment.
Set hbase.root in test/hbase-site.xml; when running a test, the default does not work consistantly.

When a HBase mini cluster is started on top of an existing mini dfs cluster, it should not shut down the mini dfs cluster when the mini HBase cluster is shut down.

TestDFSAbort catches exceptions, prints the stack trace and re-throws the exception, so you can see when the exception happened in the log.

Catch runtime exceptions that were escaping from FSUtils.isFileSystemAvailable, enabling more reliable detection of dfs failure. HRegionServer also now checks to see if it is still accepting client requests.

result

M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HConnectionManager.java
    Minor fix of a log message.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStore.java
    (COMPACTION_DIR, WORKING_COMPACTION): Removed.
    (compactdir): Renamed compactionDir.
    Removed from constructor our checking if a compaction was left undone.
    Instead, just ignore it.  When compaction reruns whatever as left on 
    filesystem will just be cleaned up and we'll rerun the compaction 
    (Likelihood of a crash mid-compaction in exactly the area where
    the compaction was recoverable are low -- more robust just redoing
    the compaction from scratch).
    (compactHelper): We were deleting HBaseRoot/compaction.tmp dir
    after a compaction completed. Usually fine but on a cluster of
    more than one machine, if two compactions were near-concurrent, one
    machine could remove the compaction working directory while another
    was mid-way through its compaction.  Result was odd failures
    during compaction of result file, during the move of the resulting
    compacting file or subsequently trying to open reader on the
    resulting compaction file (See HADOOP-1765).
    a region fsck tool).
    (getFilesToCompact): Added.
    (processReadyCompaction): Added.  Reorganized compaction so that the
    window during which loss-of-data is possible is narrowed and even

    (TODO: Add a repair tool).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java

Michael Stack ec2d29c902 HADOOP-1747 On a cluster, on restart, regions multiply assigned
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
    Removed some empty lines so I can squeeze more code into a screenful.
    (assignedRegions): Factored out some code into own methods so
    this method is made a bit shorter.  Added early returns near
    top -- if nothing to assign, etc. -- so less nesting.
    Added fix: Instead of iterating over unassignedRegions after
    all the loadings have been calculated, instead iterate over
    the locally calculated  map, regionsToAssign (Otherwise, we
    were running over the same territory each time through the
    loop and were thus giving out same region multiple times).
    (regionsPerServer, assignRegionsToOneServer,
      getRegionsToAssign): Added.

Michael Stack be33a241ce HADOOP-1644 [hbase] Compactions should not block updates
Disentangles flushes and compactions; flushes can proceed while a
compaction is happening.  Also, don't compact unless we hit
compaction threshold: i.e. don't automatically compact on HRegion
startup so regions can come online the faster.

M src/contrib/hbase/conf/hbase-default.xml
    (hbase.hregion.compactionThreashold): Moved to be a hstore property
    as part of encapsulating compaction decision inside hstore.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/HBaseTestCase.java
    Refactored.  Moved here generalized content loading code that can
    be shared by tests.  Add to setup and teardown the setup and removal
    of local test dir (if it exists).
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestCompare.java
    Added test of HStoreKey compare (It works other than one would at
    first expect).
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestSplit.java
    Bulk of content loading code has been moved up into the parent class.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HConnectionManager.java
    (tableExists): Restore to a check of if the asked-for table is in list of
    tables.  As it was, a check for tableExists would just wait on all timeouts
    and retries to expire and then report table does not exist..  Fixed up
    debug message listing regions of a table.  Added protection against meta
    table not having a COL_REGINFO (Seen in cluster testing -- probably a bug
    in row removal).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java
    Loading store files, even if it was noticed that there was no corresponding
    map file, was still counting file as valid.  Also fix merger -- was
    constructing MapFile.Reader directly rather than asking HStoreFile for
    the reader (HStoreFile knows how to do MapFile references)
    (rename): Added check that move succeeded and logging.  In cluster-testing,
    the hdfs move of compacted file into place has failed on occasion (Need
    more info).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStore.java
    Encapsulate ruling on whether a compaction should take place inside HStore.
    Added reading of the compactionThreshold her.  Compaction threshold is
    currently just number of store files.  Later may include other factors such
    as count of reference files.  Cleaned up debug messages around
    reconstruction log.  Removed compaction if size > 1 from constructor.  Let
    compaction happen after we've been deployed (Compactions that happen while
    we are online can continue to take updates.  Compaction in the constructor
    puts off our being able to take in updates).
    (close): Changed so it now returns set of store files.  This used to be done
    by calls to flush. Since flush and compaction have been disentangled, a
    compaction can come in after flush and the list of files could be off.
    Having it done by close, can be sure list of files is complete.
    (flushCache): No longer returns set of store files.  Added 'merging compaction'
    where we pick an arbitrary store file from disk and merge into it the content
    of memcache (Needs work).
    (getAllMapFiles): Renamed getAllStoreFiles.
    (needsCompaction): Added.
    (compactHelper): Added passing of maximum sequence number if already
    calculated. If compacting one file only, we used skip without rewriting
    the info file.  Fixed.
    Refactored.  Moved guts to new  compact(outFile, listOfStores)  method.
    (compact, CompactionReader): Added overrides and interface  to support
    'merging compaction' that takes files and memcache.  In compaction,
    if we failed the move of the compacted file, all data had already been
    deleted.  Changing, so deletion happens after confirmed move of
    compacted file.
    (getFull): Fixed bug where NPE when read of maps came back null.
    Revealed by our NOT compacting stores on startup.  Meant could be two
    backing stores one of which had no data regards queried key.
    (getNMaps): Renamed countOfStoreFiles.
    (toString): Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreKey.java
    Added comment on 'odd'-looking comparison.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
    Javadoc edit. 
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HLogEdit.java
    Only return first 128 bytes of value when toStringing (On cluster,
    was returning complete web pages in log).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
    Removed confusing debug message (made sense once -- but not now).
    Test rootRegionLocation for null before using it (can be null).
M  src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMemcache.java
    Added comment that delete behavior needs study.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegion.java
    Fixed merge so it doesn't do the incremental based off files
    returned by flush.  Instead all is done in the one go after
    region closes (using files returned by close).
    Moved duplicated code to new filesByFamily method.
    (WriteState): Removed writesOngoing in favor of compacting and
    flushing flags.
    (flushCache): No longer returns list of files.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/util/Writables.java
    Fix javadoc.

Michael Stack 790e3d767e HADOOP-1662 Make region splits faster
Splits are now near-instantaneous.  On split, daughter splits create
'references' to store files up in the parent region using new 'HalfMapFile'
class to proxy accesses against the top-half or bottom-half of 
backing MapFile.  Parent region is deleted after all references in daughter
regions have been let go.

Below includes other cleanups and at least one bug fix for fails adding
>32k records and improvements to make it more likely TestRegionServerAbort
will complete..

A src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestHStoreFile.java
    Added. Tests new Reference HStoreFiles. Test new HalfMapFileReader inner
    class of HStoreFile. Test that we do the right thing when HStoreFiles
    are smaller than a MapFile index range (i.e. there is not 'MidKey').
    Test we do right thing when key is outside of a HalfMapFile.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/HBaseTestCase.java
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestGet.java
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestScanner.java
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestTimestamp.java
    getHRegionDir moved from HStoreFile to HRegion.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestBatchUpdate.java
    Let out exception rather than catch and call 'fail'.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/MiniHBaseCluster.java
    Refactored so can start and stop a minihbasecluster w/o having to
    subclass this TestCase. Refactored methods in this class to use the
    newly added methods listed below.
    (MasterThread, RegionServerThread, startMaster, startRegionServers
      shutdown): Added.
    Added logging of abort, close and wait.  Also on abort/close
    was doing a remove that made it so subsequent wait had nothing to
    wait on.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestSplit.java
    Added tests that assert all works properly at region level on
    multiple levels of splits and then do same on a cluster.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestHRegion.java
    Removed catch and 'fail()'.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java
    Javadoc to explain how split now works. Have constructors flow
    into each other rather than replicate setup per instance. Moved
    in here operations such as delete, rename, and length of store files
    (No need of clients to remember to delete map and info files).
    (REF_NAME_PARSER, Reference, HalfMapFile, isReference,
      writeReferenceFiles, writeSplitInfo, readSplitInfo,
      createOrFail, getReader, getWriter, toString): Added.
    (getMapDir, getMapFilePath, getInfoDir, getInfoFilePath): Added
    a bunch of overrides for reference handling.
    (loadHStoreFiles): Amended to load references off disk.
    (splitStoreFiles): Redone to instead write references into
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStore.java
    Rename maps as readers and mapFiles as storefiles.
    Moved BloomFilterReader and Writer into HStoreFile. Removed
    getMapFileReader and getMapFileWriter (They are in HStoreFile now).
    (getReaders): Added.
    (HStoreSize): Added.  Data Structure to hold aggregated size
    of all HStoreFiles in HStore, the largest, its midkey, and
    if the HStore is splitable (May not be if references).
    Previous we only did largest file; less accurate.
    (getLargestFileSize): Renamed size and redone to aggregate
    sizes, etc.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HColumnDescriptor.java
    Have constructors waterfall down through each other rather than
    repeat initializations.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMerge.java
    Use new HStoreSize structure.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
    Added delayed remove of HRegion (Now done in HMaster as part of
    meta scan). Change LOG.error and LOG.warn so they throw stack trace
    instead of just the Exception.toString as message.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HConstants.java
    (COLUMN_FAMILY_STR): Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HLog.java
    Added why to log of splitting.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HLogEdit.java
    Short is not big enough to hold edits tha could contain a sizable
    web page.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HTable.java
    (getTableName): Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
    Added constructor to BaseScanner that takes name of table we're
    scanning (ROOT or META usually). Added to scanOneRegion handling
    of split regions.  Collect splits to check while scanning and
    then outside of the scanning, so we can modify the META table
    is needed, do the checks of daughter regions and update on
    change of state.  Made LOG.warn and LOG.error print stack trace.
    (isSplitParent, cleanupSplits, hasReferences): Added. 
    Added toString to each of the PendingOperation implementations.
    In the ShutdownPendingOperation scan of meta data, removed
    check of startcode (if the server name is that of the dead
    server, it needs reassigning even if start code is good).
    Also, if server name is null -- possible if we are missing
    edits off end of log -- then the region should be reassigned
    just in case its from the dead server.  Also, if reassigning,
    clear from pendingRegions.  Server may have died after sending
    region is up but before the server confirms receipt in the
    meta scan. Added mare detail to each log.  In OpenPendingOperation
    we were trying to clear pendingRegion in wrong place -- it was
    never executed (regions were always pending). 
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionInfo.java
    Add split boolean.  Output offline and split status in toString.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMemcache.java
    Comments.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegion.java
    Moved getRegionDir here from HStoreFile.
    (COL_SPLITA, COL_SPLITB): Added.
    (closeAndSplit): Refactored to use new fast split method.
       StringUtils.formatTimeDiff(System.currentTimeMillis(), startTime));
    (splitStoreFile): Moved into HStoreFile.
    (getSplitRegionDir, getSplitsDir, toString): Added.
    (needsSplit): Refactored to exploit new HStoreSize structure.
    Also manages notion of 'unsplitable' region.
    (largestHStore): Refactored.
    (removeSplitFromMETA, writeSplitToMETA, getSplit, hasReference): Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/util/Keying.java
    (intToBytes, getBytes): Added.
A src/contrib/hbase/src/java/org/apache/hadoop/hbase/util/Writables.java

(except TestHClient and HBaseShell) have been converted to use the new client

HBaseAdmin
- Expose connection methods getMaster, isMasterRunning and listTables

Jim Kellerman 2bbcc5a122 HADOOP-1528 HClient for multiple tables (phase 1)
Modified:

HConstants
static final Text[] COL_REGIONINFO_ARRAY = new Text [] {COL_REGIONINFO};
static final Text EMPTY_START_ROW = new Text();

HMaster
- don't process a region server exit message if the lease has timed
  out. Otherwise we end up with two pending server shutdown messages
  to process and chaos ensues.
- don't reassign the root region when the server's lease expires. The
  lease expiration handler will queue a PendingServerShutdown
  operation that must run before the root region is reassigned because
  the HLog of the dead server must be split before any regions served
  by the dead server are reassigned.
- added some additional debug level logging

HBaseClusterTestCase
- call HConnectionManager.deleteConnection(conf) in tearDown() so that
  multiple tests can be run from the same test class.

TestScanner2
- changes to make test compatible with the change from inner class
  HClient.RegionLocation to public class HRegionLocation

Leases
- cancelLease just returns if the lease is not found instead of
  throwing an IOException

New:

HConnection - an interface that describes the operations performed by
a connection implementation

HConnectionManager - manages connections for multiple HBase instances
and returns an object that implements HConnection from its static
method getConnection

HBaseAdmin - the HBase administrative methods refactored out of
HClient. Each HBaseAdmin object can control a single HBase
instance. To manipulate multiple instances, create multiple HBaseAdmin
objects. 

HTable - The data manipulation methods refactored out of HClient. Each
HTable object talks to a single table in a single HBase
instance. Create multiple HTable objects to use more than one table.

HRegionLocation - an inner class refactored out of HClient. Each
HRegionLocation has an HRegionInfo object and an HServerAddress
object.

HClient - totally re-implemented in terms of the new classes
above. HClient is now deprecated.

  server from the map of servers.
- rewrite waitOnRegionServer - now removes thread from map of threads

TestCleanRegionServerExit
- reduce Hadoop ipc client timeout and number of retries
- use rewritten stopRegionServer and waitOnRegionServer from MiniHBaseCluster
- add code to verify that failover worked
- moved testRegionServerAbort to separate test file

TestRegionServerAbort
- new test. Uses much the same code as TestCleanRegionServerExit but
  aborts the region server instead of shutting it down
  cleanly. Includes code to verify that failover worked.

hbase-site.xml (in src/contrib/hbase/src/test)
- reduce master lease timeout and time between lease timeout checks so
  that tests will run quicker.

HClient
- Major restructing of code that determines what region server to
  contact for a specific region. The main method findServersForTable
  is now recursive so that it will find the meta and root regions if
  they have not already been located or will re-find them if they have
  been reassigned and the old server can no longer be contacted.
- re-ordered administrative and general purpose methods so they are no
  longer located in seemingly random order.
- re-ordered code in ClientScanner.loadRegions so that if the location
  of the region changes, it will actually try to connect to the new
  server rather than continually trying to use the connection to the
  old server.

HLog
- use HashMap<Text, SequenceFile.Writer> instead of 
  TreeMap<Text, SequenceFile.Writer> because the TreeMap would return
  a value for a key it did not have (it was the value of another
  key). I have observed this before when the key is Text, but could
  not create a simple test case that reproduced the problem.
- added some new DEBUG level logging
- removed call to rollWriter() from closeAndDelete(). We don't need to
  start a new writer if we are closing the log.

HLogKey
- cleaned up per HADOOP-1466 (I initially modified it to add some
  debug logging which was later removed, but when I was making the
  modifications I took the opportunity to clean up the file)
- changed toString() format

HMaster
- better handling of RemoteException
- modified BaseScanner
 - now knows if it is scanning the root or a meta region
 - scanRegion no longer returns a value
 - if scanning the root region, it counts the number of meta regions
   it finds and sets a new AtomicInteger, numberOfMetaRegions when the
   scan is complete.
 - added abstract methods initialScan and maintenanceScan this allowed
   run method to be implemented in the base class.
- boolean rootScanned is now volatile
- modified RootScanner
 - moved actual scan into private method for readability (scanRoot)
 - implementation of abstract methods just call scanRoot
- add constructor for inner static class MetaRegion
- use a BlockingQueue to queue up work for the MetaScanner
- clean up handling of an unexpected region server exit
- PendingOperation.process now returns a boolean so that HMaster.run
  can determine if the operation completed or needs to be retried later
- PendingOperation processing no longer does a wait inside the process
  method since this might cause a deadlock if the current operation is
  waiting for another operation that has yet to be processed

HMsg
- removed MSG_REGIONSERVER_STOP_IN_ARRAY, MSG_NEW_REGION
- added MSG_REPORT_SPLIT

HRegionServer
- changed reportSplit to contain old region and new regions
- use IP from default interface rather than host name
- abort calls HLog.close() instead of HLog.rollWriter()

Michael Stack 655728f3bf HADOOP-1523 'Hung region servers waiting on write locks'
On shutdown, region servers and masters were just cancelling leases
without letting 'lease expired' code run -- code to clean up
outstanding locks in region server.  Outstanding read locks were
getting in the way of region server getting necessary write locks
needed for the shutdown process.  Also, cleaned up messaging around
shutdown so its clean -- no timeout messages as region servers try
to talk to a master that has already shutdown -- even when region
servers take their time going down.
M src/contrib/hbase/conf/hbase-default.xml
    Make region server timeout 30 seconds instead of 3 minutes.
    Clients retry anyways. Make so its likely region servers report
    in their shutdown message before their lease expires on master.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/Leases.java
    (closeAfterLeasesExpire): Added.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
    Added comments.
    (stop): Converted from public to default access (master shuts
    down regionservers).
    (run): Use leases.closeAfterLeasesExpire instead of leases.close.
    Changed log of main thread exit from DEBUG to INFO.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
    (letRegionsServersShutdown): Add better explaination of shutdown
    process to method doc.  Changed timeout waits from
    hbase.regionserver.msginterval to threadWakeFrequency.
    (regionServerReport): If closing, we used to immediately respond
    to region server with a MSG_REGIONSERVER_STOP.  This meant that
    we avoided handling of the region servers MSG_REPORT_EXITING sent
    on shutdown so region servers had no chance to cancel their lease
    in the master.  Reordered.  Moved sending of MSG_REGIONSERVER_STOP
    to after handling of MSG_REPORT_EXITING.  Also, in handling of
    MSG_REGIONSERER_STOP removed cancelling of leases.  Let leases
    expire normally (or get cancelled when the region server comes in
    with MSG_RPORT_EXITING).
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMsg.java
    (MSG_REGIONSERVER_STOP_IN_ARRAY): Added.
