Hello [email protected], Sai Hemanth Gantasala, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/22250
to look at the new patch set (#2).
Change subject: IMPALA-12785: Add commands to control event-processor status

IMPALA-12785: Add commands to control event-processor status
This patch extends the existing AdminFnStmt to support operations on
EventProcessor. E.g. to pause the EventProcessor:
impala-shell> :event_processor('pause');
to resume the EventProcessor:
impala-shell> :event_processor('start');
Or to resume the EventProcessor on a given event id (1000):
impala-shell> :event_processor('start', 1000);
Admin can also resume the EventProcessor at the latest event id by using
-1:
impala-shell> :event_processor('start', -1);
The command output will show the latest status of EventProcessor, e.g.
[localhost:21050] default> :event_processor('pause');
+--------------------------------------------------------------------------------+

| EventProcessor status: PAUSED. LastSyncedEventId: 34489. LatestEventId:
34489. |

If authorization is enabled, only admin users that have ALL privilege on
SERVER can run this command.
Note that resuming EventProcessor back to a previous event id is only
allowed when it's not in the ACTIVE state. Resuming EventProcessor at a
newer event id can be done on any states. The restriction comes from the
existing codes of MetastoreEventsProcessor#start(long).
A new catalogd RPC, SetEventProcessorStatus, is added for coordinators
to control the status of EventProcessor.
