      Description

      This can be revealed by tests/custom_cluster/test_concurrent_ddls.py added in https://gerrit.cloudera.org/c/14307

      If running with INVALIDATE METADATA concurrently, the DDLs may run out of attemps in CatalogServiceCatalog.waitForSyncDdlVersion() to wait for the target update being sent, no matter how large we increase the maxNumAttempts.

      The error logs:
