["Elliott Clark (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-4046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286186#comment-13286186 ] 

Elliott Clark commented on HBASE-4046:
--------------------------------------

Looks good.  Though it might be worth it to use atomic int's and longs for the new counters so that most of the new methods can drop their synchronized attribute.
