Subject [jira] [Commented] (HBASE-9568) backport HBASE-6508 to 0.94
Date Fri, 10 Apr 2015 06:34:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14489029#comment-14489029

Yu Li commented on HBASE-9568:
------------------------------

We're using v94 in our product environment and decided to backport HBASE-6508 to our code
base as an improvement to the none-DistributedLogReplay way, and when referring to this patch,
we found 2 issues:

# in HRegion.java, DEEP_OVERHEAD shouldn't be updated (no additional AtomicLong introduced
in the patch)
# in HLogSplitter.java, HRegionServer instance is passed to the constructor but not assigned
to the local variable, which  is a fatal issue

I understand that this improvement is less necessary after DistributedLogReplay is introduced,
but just in case anyone still want to backport it just like we do :-)
