Andrew Purtell commented on HBASE-18796: ---------------------------------------- I'm running full test suites for HBASE-18786. I have rolled in the addendums as separate commits in those working branches so will test them both together. If good I will commit them. Thanks for the addendum [~abhishek.chouhan] and thanks for pointing out the issue [~ted_yu] > Admin#isTableAvailable returns incorrect result before daughter regions are > opened > ---------------------------------------------------------------------------------- > > Key: HBASE-18796 > URL: https://issues.apache.org/jira/browse/HBASE-18796 > Project: HBase > Issue Type: Bug > Affects Versions: 1.3.1 > Reporter: Abhishek Singh Chouhan > Assignee: Abhishek Singh Chouhan > Fix For: 2.0.0, 3.0.0, 1.4.0, 1.3.2, 1.5.0 > > Attachments: HBASE-18796-addendum.branch-1.patch, > HBASE-18796-addendum.master.patch, HBASE-18796.branch-1.001.patch, > HBASE-18796.branch-1.001.patch, HBASE-18796.branch-1.002.patch, > HBASE-18796.branch-1.003.patch, HBASE-18796.master.001.patch > > > Admin#isTableAvailable checks if it can getServerName for the meta entries it > reads. During the time of split server location are added to the meta entries > in MetaTableAccessor#splitRegion although the description of the method says > "Does not add the location information to the daughter regions since they are > not open yet.". At this point during the split daughter regions are not > actually open, so we can get to a state where parent is offline, daughters > are not yet open but isTableAvailable returns true. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
