Subject [jira] [Commented] (HBASE-7592) HConnectionManager.getHTableDescriptor() compares too much
Date Thu, 17 Jan 2013 12:34:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556122#comment-13556122

Matteo Bertozzi commented on HBASE-7592:
----------------------------------------

I was thinking to a compatibility issue with someone that doesn't have the overload with the
list as argument, but looking at the history the overload is there since the first implementation.
