Subject [jira] [Updated] (PHOENIX-4764) Cleanup metadata of child views for a base table that has been dropped
Date Tue, 13 Nov 2018 20:00:00 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-4764?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas D'Silva updated PHOENIX-4764:
------------------------------------
    Description: 
Add a new SYSTEM.TASK table that is used to keep track of tables which have been dropped but
whose child view metadata hasn' been deleted yet. 
Add a scheduled task that queries this table periodically and drops the child view metadata.


  was:
When we drop a base table, we no longer drop all the child view metadata. 

Clean up the child view metadata during compaction. 

If we try to recreate a base table that was previously dropped but whose child view metadata
wasn't cleaned up throw an exception. Add a test for this.
