Subject [jira] [Created] (HIVE-16382) Find a way to store the query string only once in ZooKeeper locks

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

             Summary: Find a way to store the query string only once in ZooKeeper locks
                 Key: HIVE-16382
                 URL: https://issues.apache.org/jira/browse/HIVE-16382
             Project: Hive
          Issue Type: Improvement
          Components: Locking
    Affects Versions: 3.0.0
            Reporter: Peter Vary


Currently when we store the locks in ZooKeeper, then every lock object contains the query
string. HIVE-16334 aims to lessen the memory pressure on ZooKeeper by adding the possibility
to store only the truncated version of the query string.

It would be even better to find a solution for storing the string only once, or not at all,
but still be able to provide it when they are queried by the SHOW LOCKS EXTENDED.
