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
then, we log a message with how a restore might be performed manually
(TODO: Add a repair tool).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java
(rename): More checking around rename that it was successful.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HLog.java
An empty-log gives HLog trouble. Added handling.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
Cleanup of debug level logging.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegion.java
Minor javadoc and changed a log from info to debug.
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@569446 13f79535-47bb-0310-9956-ffa450edef68
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.
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@568404 13f79535-47bb-0310-9956-ffa450edef68

Use new HColumnDescriptor accessors rather than make direct accesses
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HColumnDescriptor.java
(COMPRESSION_NONE, COMPRESSION_RECORD, COMPRESSION_BLOCK): Removed.
Use enum ordinals instead. Removed mapping between these defines and
enum equivalents. Made data members private and added accessors.
(DEFAULT_IN_MEMORY, DEFAULT_COMPRESSION_TYPE,
DEFAULT_BLOOM_FILTER_DESCRIPTOR, DEFAULT_MAX_VALUE_LENGTH): Added.
M hbase/src/test/org/apache/hadoop/hbase/TestToString.java
Fix because enum strings are upper-case (was expecting lowercase).
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@568275 13f79535-47bb-0310-9956-ffa450edef68
Added handling for legal null value scanning META table and added
logging of unexpected exceptions that arise scanning.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestSplit.java
Refactored to do a staged removal of daughter references.
(compact, recalibrate): Added.
(getSplitParent): Refactored as getSplitParentInfo.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HConnectionManager.java
Added formatting of the find table result string so shorter
(when 30-odd regions fills page with its output).
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HTable.java
Formatting to clean eclipse warnings.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
The split column in a parent meta table entry can be null (Happens
if a daughter split no longer has references -- it removes its
entry from parent). Add handling and clean up around split
management code. Added logging of unexpected exceptions
scanning a region.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegion.java
Added fix for NPE when client asks for scanner but passes
non-existent columns.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/util/Writables.java
(getHRegionInfo, getHRegionInfoOrNull): Added.:
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@567308 13f79535-47bb-0310-9956-ffa450edef68
HADOOP-1725 Client find of table regions should not include offlined, split parents
Changes:
New class MapWritable replaces KeyedData and KeyedDataArrayWritable
HBaseAdmin, HConnectionManager, HMaster, HRegionInterface,
HRegionServer, HTable, TestScanner2:
- getRow returns MapWritable instead of array of KeyedData
- next returns MapWritable instead of array of KeyedData
GroupingTableMap, IdentityTableMap, IdentityTableReduce,
TableInputFormat, TableMap, TableOutputCollector, TableOutputFormat,
TestTableMapReduce:
- use MapWritable instead of KeyedData and KeyedDataArrayWritable
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@566878 13f79535-47bb-0310-9956-ffa450edef68
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.
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@566459 13f79535-47bb-0310-9956-ffa450edef68
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.

HTable
* added public method close
* added protected method checkClosed

git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@562294 13f79535-47bb-0310-9956-ffa450edef68
(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
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.
git-svn-id: https://svn.apache.org/repos/asf/lucene/hadoop/trunk/src/contrib/hbase@561935 13f79535-47bb-0310-9956-ffa450edef68
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()

hbase.regionserver.handler.count): Add values that are less than
default so unit tests are even more responsive (and finished quicker).
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestToString.java
Change test so it expects region info name that has ',' delimiters
rather than '_' delimiters.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestTable.java
Rename testTable as testCreateTable.
(testTableNameClash): Test for this issue.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionInfo.java
Change format of region names so delimiter is ',' rather than '_'.

M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestTable.java
(testTable): Add checking of actual exceptions thrown and
assertions that we are getting right behavior. Add a test
that has ten clients concurrently trying to create same table.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HClient.java
javadoc edit. Fix debug message that could give impression
table was found when it wasn't.

Added comment on table nameing.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
(createTable): Refactored. Bulk moved to a private override.
Changed how check for existance is done.
M rc/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionInfo.java
(getTableNameFromRegionName): Utility method added.

M src/contrib/hbase/NOTICE.txt
Add notice of udanax contributions.
Msrc/contrib/hbase/conf/hbase-default.xml
(hbaseshell.jline.bell.enabled): Added.
M src/contrib/hbase/CHANGES.txt
(hadoop-1375) Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/package.html
Add note on how to start up hbase shell
M src/contrib/hbase/bin/hbase
Add 'shell'. Remove 'client' (shell does what it used do and more).
Removed all reader and logreader until better developed. Starting
up a reader or logreader on a running hbase system could do damage).
M src/contrib/hbase/build.xml
Add a javacc target to generate content of shell/generated subpackage.
