Subject [jira] [Commented] (HBASE-18614) Setting BUCKET_CACHE_COMBINED_KEY to false disables stats on RS UI
Date Tue, 22 Aug 2017 23:01:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16137565#comment-16137565
] 

Ted Yu commented on HBASE-18614:
--------------------------------

{code}
-        bucketCacheReport(sbc);
+       LOG.info(bc.getClass().getSimpleName() + ": " + sbc.getStats());
{code}
Is the above change necessary ?
