[VOTE] The 2nd HBase 0.98.0 release candidate is available for download
The 2nd HBase 0.98.0 release candidate (RC1) is available for download at
http://people.apache.org/~apurtell/0.98.0RC1/ and Maven artifacts are also
available in the temporary repository
https://repository.apache.org/content/repositories/orgapachehbase-1003
Signed with my code signing key D5365CCD.
HBase 0.98.0 is the next major release after HBase 0.96. It is expected to
be wire compatible with HBase 0.96, so clients and servers mixed between
these versions will seamlessly interoperate, provided new features
available in 0.98 are not enabled. However, the HBase 0.98.0 release is not
intended to be binary compatible at the Java API level with any HBase 0.96
release or earlier. You may need to recompile applications which reference
the HBase JARs. Users of HBase 0.94 will have to perform an offline data
migration procedure during upgrade. Consult the HBase Online Manual for
more information. It is not necessary to migrate data from 0.94 to 0.98
through 0.96, you can upgrade from 0.94 to 0.98 directly if desired
following the same procedure for upgrading from 0.94 to 0.96.
This release includes several new security features like per-cell
visibility labels, per-cell ACLs, transparent encryption, and related
changes to the coprocessor framework. Please see the Security section of
the HBase Online Manual for more information. There are significant
performance improvements, such as a change to the write ahead log (WAL)
threading model that provides higher transaction throughput under high
load, reverse scanners, MapReduce over snapshot files, and striped
compaction. The list of changes in this release can be found here:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12323143
Please try out the candidate and vote +1/-1 by midnight Pacific Time (00:00
-0800 GMT) on February 5 on whether or not we should release this as
0.98.0.

Unfortunately we've found an issue that is a blocker for RC1 because a
default setting must be changed. See HBASE-10443 (IndexOutOfBoundExceptions
when processing compressed tags in HFile)
