Sai Hemanth Gantasala updated IMPALA-12547:
-------------------------------------------
Description:
Set the default worker threads for compaction to 1.
Currently worker threads for compaction to 4, as a result, in the external
frontend mode, there are a lot of calls to HMS in idle state. So, it is
flooding the catalogD log with unnecessary calls to HMS.

was:
Set the default worker threads for compaction to 1. Also, set the worker sleep
time to 60000ms.
Currently worker threads for compaction to 4, as a result, in the external
frontend mode, there are a lot of calls to HMS in idle state. So, it is
flooding the catalogD log with unnecessary calls to HMS.
