Subject [jira] [Commented] (PHOENIX-886) error when drop table
Date Wed, 16 Apr 2014 17:28:19 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13971695#comment-13971695

----------------------------------------

Github user JamesRTaylor commented on the pull request:

    https://github.com/apache/incubator-phoenix/pull/29#issuecomment-40627413
  
    Thanks for the pull request. The code is written this way to avoid making multiple admin
calls. Plus, even if you checked up front, you'd still have the possibility for the exception
to occur, as the table may get removed right after you check that it exists.
