Subject [jira] [Commented] (HBASE-9457) Master could fail start if region server with system table is down
Date Sun, 15 Sep 2013 22:28:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13767939#comment-13767939
] 

Francis Liu commented on HBASE-9457:
------------------------------------

I'm +1. Tho I'm wondering are there any backwards compatibility gotchas if when we move namespace
table from one wal to another? It seems we could just flush the namespace table and perform
rolling restart to do an upgrade.

> In the region server holding the system table is killed while master is starting, master
will hang there waiting for system table to be assigned which won't happen.
