----------------------------------------------
Summary: Set the default worker threads for compaction to 1
Key: IMPALA-12547
URL: https://issues.apache.org/jira/browse/IMPALA-12547
Project: IMPALA
Issue Type: Wish
Components: fe
Reporter: Sai Hemanth Gantasala
Assignee: Sai Hemanth Gantasala
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.

After the above-proposed values for the configs, this is the log info in an
idle state.
