Subject [jira] Issue Comment Edited: (HBASE-1508) Shell "close_region" reveals a Master<>HRS problem, regions are not reassigned
Date Sat, 20 Jun 2009 17:50:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12722226#action_12722226

-----------------------------------------------------------------

A workaround from the shell is 'enable <table>' after issuing the close_region command.
This causes the master to discover the offline region and attempt to reassign.

> But that is it, no further processing is done. The regions stays closed, and even across
a restart it stays closed. 
> According to what I got told the region should be automatically reassigned to a new server.
Please confirm that this is what is expected. If not and the above seems right, then please
disregard and close issue.
