Subject [jira] [Commented] (HBASE-6881) All regionservers are marked offline even there is still one up
Date Tue, 25 Sep 2012 20:06:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13463162#comment-13463162
] 

Jimmy Xiang commented on HBASE-6881:
------------------------------------

This is NOT an issue caused by HBASE-6438 actually. I fixed the description.  It is an existing
issue.

During unit test, there could be just one region server. This can lead to HBASE-6880, and
hanging tests.
