Subject [jira] [Commented] (HBASE-12746) [1.0.0RC0] Distributed Log Replay is on (HBASE-12577 was insufficient)
Date Tue, 23 Dec 2014 06:37:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14256660#comment-14256660
] 

stack commented on HBASE-12746:
-------------------------------

Test fail locally for me too so more work to do.  Looking at TestOfflineMetaRebuildBase, we
are stuck here after 'recovering' three servers that had no logs in them (I've seen this before...
it makes us think we are joining an existing cluster but its actually clean start):

> It says DLR is on.  HBASE-12577 was not enough it seems.  The hbase-default.xml still
has DLR as true.
