Hello Quanlong Huang, Csaba Ringhofer, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21665
to look at the new patch set (#6).
Change subject: IMPALA-12865: enable_reload_events breaks
enable_skipping_older_events by pushing lastRefreshEventId too high
......................................................................
IMPALA-12865: enable_reload_events breaks enable_skipping_older_events
by pushing lastRefreshEventId too high
When enable_reload_events is true, catalogd fires RELOAD events after
REFRESH finishes reloading the table/partition. The RELOAD event id is
also used to update lastRefreshEventId of the table/partition. This is
problematic when enable_skipping_older_events is true. HMS events
generated after the reload and before the RELOAD event will be skipped.
Solution:
Fetch the current HMS notification event id before the table/partition
is refreshed, and set it as lastRefreshEventId on the metadata object.
Testing:
- Manually verified the issue is addressed.
- Added an end-to-end test which is close to real time issue.
