Work Description: pvary commented on PR #4252:
URL: https://github.com/apache/hive/pull/4252#issuecomment-1523621934
> @InvisibleProgrammer Thanks for sharing your thought! The two commits
`fede493d59f17ff2bfc0744b296d90bd36130386` and
`333227fbd13821365cec1bdbfcb9314a239bea0f` are realy hard to deal. We shoud
carefully handle these commits. I also hope the author of two commits can give
us some info to evaluate if it is very necessary to port in current Hive
`iceberg-handler` moduel @pvary .
There is a new commit which could be helpful, because it removes the need to
issue a HiveLock on alter table:
- c3232b664745ebf761b6a74f4c5b55cc48bfd209: Hive: Use EnvironmentContext
instead of Hive Locks to provide transactional commits after HIVE-26882 - This
is based on 333227fbd13821365cec1bdbfcb9314a239bea0f and
fede493d59f17ff2bfc0744b296d90bd36130386. Has to be a parallel change on
Hive/Impala and every writers of the Iceberg table, but fixes stability and
enhances commit performance
- 333227fbd13821365cec1bdbfcb9314a239bea0f - Hive: Refactor commit lock
mechanism from HiveTableOperations. This is mostly a refactoring to make it
possible to do c3232b664745ebf761b6a74f4c5b55cc48bfd209
- fede493d59f17ff2bfc0744b296d90bd36130386 - Hive: Lock hardening (#6451) -
makes sure that the Lock used by the Iceberg commit are cleared up... If you do
not have stability issues with stuck Hive Locks then you might skip backporting
it.
