[jira] [Commented] (HBASE-7034) Bad version, failed OPENING to
OPENED but master thinks it is open anyways
[ https://issues.apache.org/jira/browse/HBASE-7034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13482160#comment-13482160 ]
ramkrishna.s.vasudevan commented on HBASE-7034:
-----------------------------------------------
@Stack
This happens in 0.94.2? Which RS failed in transitioning the node to OPENED? new one or the one which already transitioned to OPENED?
Sorry for the questions as there are no full logs i had these doubts. Thanks Stack for reporting this, it should be useful for us also.
