Subject [jira] [Updated] (HBASE-10844) Coprocessor failure during batchmutation leaves the memstore datastructs in an inconsistent state
Date Thu, 13 Aug 2015 23:29:46 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10844?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nick Dimiduk updated HBASE-10844:
---------------------------------
    Attachment: HBASE-10844.02-0.98.patch
                HBASE-10844.02-branch-1.0.patch
                HBASE-10844.02.patch

Cleaned up patch for master. HBASE-10844.02.patch compiles for master, branch-1, branch-1.2,
branch-1.1. Patch from master does not cherry-pick cleanly any further back, so branches branch-1.0
and 0.98 get their own patches. Just accounting for minor fuzz in the assert line.

> Observed this in the testing with Phoenix. The test in Phoenix - MutableIndexFailureIT
deliberately fails the batchmutation call via the installed coprocessor. But the update is
not rolled back. That leaves the memstore inconsistent. In particular, I observed that getFlushableSize
is updated before the coprocessor was called but the update is not rolled back. When the region
is being closed at some later point, the assert introduced in HBASE-10514 in the HRegion.doClose()
causes the RegionServer to shutdown abnormally.
