             Summary: Set catalogd /healthz OK before we load the UDFs
                 Key: IMPALA-13855
                 URL: https://issues.apache.org/jira/browse/IMPALA-13855
             Project: IMPALA
          Issue Type: Bug
          Components: Catalog
            Reporter: Wenzhe Zhou


In a user case, there are lots of UDFs which are loaded when catalogd is 
started.
This heavy function loading affect health check and cause catalogd being 
restarted.
To avoid this issue, we should set /healthz OK for catalogd much before we load 
the UDFs.
