[jira] [Commented] (PHOENIX-2787) support IF EXISTS for ALTER TABLE SET options

    [ https://issues.apache.org/jira/browse/PHOENIX-2787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16708758#comment-16708758 ] 

Hans Deragon commented on PHOENIX-2787:
---------------------------------------

This feature request should be more generic.  "IF EXISTS" should work with any "ALTER TABLE" options.  Should also work, for example, with "RENAME TO".  Agree to change the description?  I let the author of this feature request to do so.
