Patch Set 2: (1 comment) http://gerrit.cloudera.org:8080/#/c/23687/2/be/src/catalog/catalog-server.cc File be/src/catalog/catalog-server.cc: http://gerrit.cloudera.org:8080/#/c/23687/2/be/src/catalog/catalog-server.cc@261 PS2, Line 261: DEFINE_bool(enable_hierarchical_event_processing, true, > We need to reduce hms_event_polling_interval_s to < 1sec. Since multiple th If we set hms_event_polling_interval_s to 0.2s, then we would hit metastore 5 times every 1 second, compared to 1 time per second currently (In the Ideal case), which puts additional stress on metastore on an already busy cluster.
