+1 - checked documentation and tarball
- Ran in local and distributes mode - checked the UI pages - loaded 100m KeyValues - tested scan performance - converted between FAST_DIFF and NONE encoding - tested flushes and compactions -- Lars ________________________________ From: lars hofhansl <[email protected]> To: hbase-dev <[email protected]> Sent: Tuesday, February 18, 2014 8:31 PM Subject: [VOTE] The 2nd hbase 0.94.17 release candidate is available for download The 2nd 0.94.17 RC is available for download at http://people.apache.org/~larsh/hbase-0.94.17-rc1/ Signed with my code signing key: C7CFE328 HBase 0.94.17 is a bug fix release with 35 fixes: [HBASE-7963] - HBase VerifyReplication not working when security enabled [HBASE-10249] - TestReplicationSyncUpTool fails because failover takes too long [HBASE-10274] - MiniZookeeperCluster should close ZKDatabase when shutdown ZooKeeperServers [HBASE-10319] - HLog should roll periodically to allow DN decommission to eventually complete.

The list of changes is also available here: https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12325845 Here're the jenkins runs for this RC: https://builds.apache.org/job/HBase-0.94.17/15/ and https://builds.apache.org/job/HBase-0.94.17-security/5/ Please try out the RC, check out the doc, take it for a spin, etc, and vote +1/-1 by EOD February 24th on whether we should release this as 0.94.17. As before, I realize that release testing is like pulling teeth, but please give this is quick run, so we can get these bug fixes out there. Thanks. -- Lars
