Subject [jira] [Commented] (HBASE-7592) HConnectionManager.getHTableDescriptor() compares too much
Date Thu, 17 Jan 2013 08:40:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13555983#comment-13555983
] 

Maryann Xue commented on HBASE-7592:
------------------------------------

Is there any specific reason why we can't simply call the other interface "HMaster#getHTableDescriptors(List<String>)"
instead of retrieving all table descriptors over the network?
