Hello Quanlong Huang, Csaba Ringhofer, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21662
to look at the new patch set (#2).
Change subject: IMPALA-12758: Event processor is ignoring the prev_id while
reloading existing partitions
......................................................................
IMPALA-12758: Event processor is ignoring the prev_id while reloading
existing partitions
IMPALA-10976 depends on event processor for cache consistency instead
of directly modifying the cache inplace. so when
enable_sync_to_latest_event_on_ddls is enabled, cache modification via
partitioned table events should retain the prev_id of the partitions
while reloading the partitions. Currently, prev_id is set to -1, so
when the catalogDelta is sent from the state store to impala demons,
because prev_id is not valid, impalads will not know whether to
invalidate the current partition and then request the new partition
information.
This patch addresses this issue by setting the prev_id of reloaded
partition.
Note: This is only an issue when
enable_sync_to_latest_event_on_ddls is enabled
Testing:
- Added an ened-to-end test to verify the same
