Thejas M Nair updated HIVE-4470:
--------------------------------
Description:
Hive can run queries in local mode (instead of using a cluster), if the size is
small. This happens when "hive.exec.mode.local.auto" is set to true.
This would affect the stability of the hive server2 node, if you have heavy
query processing happening on it. Bugs in udfs triggered by a bad record can
potentially add very heavy load making the server inaccessible.
By default, HS2 should set these parameters to disallow local execution or send
and error message if user tries to set these.
