Hi Devs Regarding the 0.90.6 release i would like share few things about the issues that were added to it
-> HBASE- 5008 - The clusters can't provide services because Region can't flush. <https://issues.apache.org/jira/browse/HBASE-5008> -> HBASE- 5060 - HBase client is blocked forever <https://issues.apache.org/jira/browse/HBASE-5060> -> HBASE-5088 - A concurrency issue on SoftValueSortedMap <https://issues.apache.org/jira/browse/HBASE-5088> -> HBASE-5009 - Failure of creating split dir if it already exists prevents splits from happening further <https://issues.apache.org/jira/browse/HBASE-5009> -> HBASE-5073 - Registered listeners not getting removed leading to memory leak in HBaseAdmin <https://issues.apache.org/jira/browse/HBASE-5073> -> HBASE-5137 - MasterFileSystem.splitLog() should abort even if waitOnSafeMode() throws IOException <https://issues.apache.org/jira/browse/HBASE-5137> -> HBASE-5178 - Backport HBASE-4101 - Regionserver Deadlock <https://issues.apache.org/jira/browse/HBASE-5178> The above are some important issues that are committed. Apart from these we have few more important defects committed. Issues HBASE-5179 - Concurrent processing of processFaileOver and ServerShutdownHandler may cause region to be assigned before log splitting is completed, causing data loss <https://issues.apache.org/jira/browse/HBASE-5179> HBASE-5155 - ServerShutDownHandler And Disable/Delete should not happen parallely leading to recreation of regions that were deleted <https://issues.apache.org/jira/browse/HBASE-5155> are in progress. We have also backported some of the critical issues from trunk like HBASE-4899 - Region would be assigned twice easily with continually killing server and moving region in testing environment <https://issues.apache.org/jira/browse/HBASE-5156> HBASE-5152 - Region is on service before completing initialization when doing rollback of split, it will affect read correctness <https://issues.apache.org/jira/browse/HBASE-5184> HBASE-4878 - Master crash when splitting hlog may cause data loss <https://issues.apache.org/jira/browse/HBASE-5158> I would like to take a release cut of this version by tomorrow EOD (i.e. Saturday morning as per US time). Pls share your comments. Regards Ram
