Fix Version/s: (was: 0.94.0)

I suppose Li is back to course work, and nobody will pick this up in time for 0.94. Moving out.

[jira] [Commented] (HBASE-4258) Metrics panel for the Off Heap
Cache
Posted by "Ted Yu (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-4258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13105842#comment-13105842 ]
Ted Yu commented on HBASE-4258:
-------------------------------
Should metrics.blockCacheFree be called metrics.blockCacheFreeSize ?
For:
{code}
+ DoubleBlockCache castedCache = (DoubleBlockCache) blockCache;
{code}
We should either call it castCache, or better yet, doubleBlockCache.
See http://wiki.answers.com/Q/Past_tense_of_cast
Overall, patch looks good.
Mind sharing some screenshot(s) of the new metrics, Li ?
