Description

We observed that the event processor is broken after receiving a partition event for materialized views (MV). This is because we are treating MV as view in Impala and hive generates partition events for MV, which breaks current event processor.

In this patch, we let events of MV follow the code path of ACID tables to reload the view. In the long term, we will need IMPALA-10723 to treat materialized view as a table.
