Anurag Mantripragada has uploaded a new patch set (#19). ( http://gerrit.cloudera.org:8080/12889 )
Change subject: IMPALA-7971: Add support for insert events in event processor. ...................................................................... IMPALA-7971: Add support for insert events in event processor. This patch adds support for detecting and processing insert events triggered by impala as well as external engines (eg.Hive). Inserts from Impala will fire an insert event notification. Using this event, event-processor will refresh table/partition. Both insert into and overwrite are supported for tables/partitions. Known Issues: 1. Inserts into tables from Hive are ignored by the event processor as these inserts create an ALTER event first followed by an INSERT event. The alter will invalidate table making the refresh a no-op. Insert into partitions from hive will create an INSERT event first followed by an ALTER event. In this case, there is an unnecessary table invalidate after a refresh. 2. Existing self-events logic cannot be used for insert events since firing insert event does not allow us to modify table parameters in HMS. This means we cannot get the CatalogServiceIdentifiers in insert events. Therefore, the event-processor will also refresh the tables for which insert operation is performed through Impala. Testing: 1. Added new custom cluster tests to run different insert commands from hive and verified new data is available in Impala without invalidate metadata. 2. Added a test in MetastoreEventsProcessor for testing insert events.
