Subject [jira] [Commented] (HBASE-8750) MetaServerShutdownHandler stucks if .META. assignment fails in previous attempt
Date Sun, 16 Jun 2013 18:45:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13684734#comment-13684734

Himanshu Vashishtha commented on HBASE-8750:
--------------------------------------------

8705 adds retries for assigning meta; if regionserver comes up after exhausting the retries,
the problem will still be there.

> While running log replay on a one node setup, I killed meta regionserver. The MetaSSH
tries to assign the meta table, but it failed as there was no other regionservers to assign
to. But the meta server znode was already updated to null. When the assignment fails, the
metaSSH is retried. But from the next iteration, it will not try to assign the meta region,
but keeps on waiting for meta region. This keeps on going even after regionserver is brought
up again.
