---------------------------------------
Summary: Add flag to configure the default value of
"impala.disableHmsSync"
Key: IMPALA-14131
URL: https://issues.apache.org/jira/browse/IMPALA-14131
Project: IMPALA
Issue Type: New Feature
Components: Catalog
Reporter: Quanlong Huang
Users might want to roll out EventProcessor job by job and turn it off on all
db/tables by default. It's tedious to set "impala.disableHmsSync" to "true" on
all dbs. If a db has some tables that want to turn event processing on, users
should set "impala.disableHmsSync" to "true" on all other tables in that db,
which is also tedious.
We need a catalogd startup flag like disable_hms_sync_by_default which is the
default value of "impala.disableHmsSync" when it's missing in db/table
properties. It's independent to hms_event_polling_interval_s that catalogds
will still poll HMS events based on hms_event_polling_interval_s, but if
disable_hms_sync_by_default is true, events on all db/tables will be skipped
unless the db/table has property "impala.disableHmsSync"="false".
