Peter Vary created HIVE-16334:
---------------------------------
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
