Subject [jira] [Commented] (HBASE-9037) LruBlockCache is too verbose at Debug level
Date Thu, 25 Jul 2013 04:57:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13719227#comment-13719227
] 

Lars Hofhansl commented on HBASE-9037:
--------------------------------------

So in trunk we'd see *more* of these messages as the difference between min and max is smaller.

I think I should just mark this as invalid.
