Subject The 3nd HBase 0.98.6 release candidate (RC2) is available, vote closing 9/10/2014
Date Thu, 04 Sep 2014 04:53:53 GMT
​The 3nd HBase 0.98.6 release candidate (RC2) is available for download at
​​​https://people.apache.org/~apurtell/0.98.6RC2/ and Maven artifacts are
also available in the temporary repository
https://repository.apache.org/content/repositories/orgapachehbase-1035

Signed with my code signing key D5365CCD.

The issues resolved in this release can be found here:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12327376

This candidate contains a significant backported change, ZK-less region
assignment (HBASE-11546), thanks to the heavy lifting of Virag Kothari (and
original contributors Jimmy Xiang and Virag Kothari). The new code will not
be active unless the configuration setting "hbase.assignment.usezk" is set
to 'false'. If possible please consider testing with this configuration
change on a cluster and/or with the integration tests.

Please pardon that we've had a little trouble getting this out the door so
far. This latest 0.98.6 RC is much better for it. Though, hopefully will be
the last until 0.98.7 next month. Since RC0 the following important fixes
and improvements have gone in. Thanks to all of the reporters,
contributors, and testers involved.

   - HBASE-11726 Master should fail-safe if starting with a pre 0.96 layout
   - HBASE-11788 hbase is not deleting the cell when a Put with a KeyValue,
   KeyValue.Type.Delete is submitted
   - HBASE-11790 Bulk load should use HFileOutputFormat2 in all cases
   - HBASE-11837 Scanner from
   RegionCoprocessorEnvironment.getTable(TableName) returns no local data
   - HBASE-11844 region_mover.rb load enters an infinite loop if region
   already present on target server
   - HBASE-11857 Restore ReaderBase.initAfterCompression() and
   WALCellCodec.create(Configuration, CompressionContext)
   - HBASE-11865 Result implements CellScannable; rather it should BE a
   CellScanner
   - HBASE-11868 Data loss in hlog when the hdfs is unavailable
   - HBASE-11876 RegionScanner.nextRaw(...) should not update metrics
   - HBASE-11878
   TestVisibilityLabelsWithDistributedLogReplay#testAddVisibilityLabelsOnRSRestart
   sometimes fails due to VisibilityController not yet initialized
   - HBASE-11886 The creator of the table should have all permissions on
   the table
   - HBASE-11887 Memory retention in branch-1; millions of instances of
   LiteralByteString for column qualifier and value

I have done some initial brief qualification of this RC:

   - Unit test suite passes 100% after 3 iterations with Java 7u65

   - Untarred hadoop1 and hadoop2 convenience binaries, ran LoadTestTool,
   no unexpected logs or results

Please try out the candidate and vote +1/-1 by midnight Pacific Time (00:00
-0800 GMT) on September 10 on whether or not we should release this as
0.98.6. Three +1 votes from PMC will be required to release.
