Subject [jira] [Commented] (PHOENIX-4219) Index gets out of sync on HBase 1.x
Date Wed, 27 Sep 2017 05:24:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16181994#comment-16181994

James Taylor commented on PHOENIX-4219:
---------------------------------------

Strange that the behavior is different in 0.98 versus 1.x. The test does not even mutate the
same rows. It's essentially immutable data. It looks to be related to covered columns as it
passes in master if the index has no covered columns.

> When writing batches in parallel with multiple background threads, it seems the index
sometimes gets out of sync.  This only happens on the master and 4.x-HBase-1.2.
> The tests pass for 4.x-HBase-0.98
> See the attached test, which writes with 2 background threads with batch size of 100.
