Subject [jira] Commented: (HBASE-2830) NotServingRegionException shouldn't log a stack trace
Date Mon, 12 Jul 2010 18:58:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12887469#action_12887469
] 

Patrick Angeles commented on HBASE-2830:
----------------------------------------

Another instance of this. I also noticed that it's ERROR level in one place, and INFO level
here. Maybe DEBUG is the right level?
