Change subject: IMPALA-8579: Ignore trivial alter table/partition events. ...................................................................... IMPALA-8579: Ignore trivial alter table/partition events. Hive generates certain trivial alter events for eg: change only "transient_lastDdlTime". This is seen in the alter events accompanying an INSERT event. MetastoreEventProcessor should ignore such events as these trivial properties are not used by Impala and they cause unnecessary invalidates/refreshes. This change will also potentially reduce the likelihood of IMPALA-8877 as back to back invalidates after INSERT operations are avoided. Testing: Added tests respectively to testPartitionEvents() and testAlterTableEvent() in MetastoreEventProcessorTest class.
