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
Utility reading and writing Writables.

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.
