Jim Kellerman fa1c77bd3e HADOOP-2079 HADOOP-2056 Fix generated HLog, HRegion names
HLog.splitLog was generating incorrect file names, HRegion was generating file names that could be far too long especially for local file systems, HMaster had a race condition in which an old HLog would get split by two threads simultaneously.

Jim Kellerman cc202c4b74 HADOOP-2056 A table with row keys containing colon fails to split regions
Many modifications required because region names (which contain start key) were used as file or directory names. Now the startKey is encoded in an order preserving Base64 dialect.

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

    (TODO: Add a repair tool).

    were running over the same territory each time through the

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

    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.

HConnectionManager

    * a call to getTableServers or reloadTableServers will cause information for closed
      tables to be reloaded

Jim Kellerman 84ef0ba801 HADOOP-1528 HClient for multiple tables (phase 2) all HBase client side code
(except TestHClient and HBaseShell) have been converted to use the new client
side objects (HTable/HBaseAdmin/HConnection) instead of HClient.

HBaseAdmin
- Expose connection methods getMaster, isMasterRunning and listTables



git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@562041 13f79535-47bb-0310-9956-ffa450edef68
2007-08-02 08:15:26 +00:00
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.

Jim Kellerman 5f850fcee4 HADOOP-1516 HClient fails to readjust when ROOT or META redeployed on new region server
Detailed changes:

MiniHBaseCluster
- rewrite abortRegionServer, stopRegionServer - they now remove the
  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.
