             Summary: Dropping a view checks whether it has child views which 
has to be done only when a table is dropped 
                 Key: PHOENIX-2050
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2050
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.3.1
            Reporter: Arun Kumaran Sabtharishi
             Fix For: 4.3.1


Whenever a view is dropped, MetaDataEndPointImpl.findChildViews() checks 
whether it has child views or not. This is doing a full scan in all the rows in 
SYSTEM.CATALOG which reduces performance. When the number of rows is very high, 
it causes timeout. The check has to be done only for the tables.
