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

             Summary: Query lock contains the query string, which can cause OOM 
on ZooKeeper
                 Key: HIVE-16334
                 URL: https://issues.apache.org/jira/browse/HIVE-16334
             Project: Hive
          Issue Type: Improvement
          Components: Locking
            Reporter: Peter Vary
            Assignee: Peter Vary


When there are big number of partitions in a query this will result in a huge 
number of locks on ZooKeeper. Since the query object contains the whole query 
string this might cause serious memory pressure on the ZooKeeper services.

It would be good to have the possibility to truncate the query strings that are 
written into the locks
