I'd like you to reexamine a change. Please visit

to look at the new patch set (#6).
Change subject: IMPALA-12719: Reload filemetadata for AlterTable event of type
truncate
......................................................................
IMPALA-12719: Reload filemetadata for AlterTable event of type truncate
When the event processor receives an alter table event and the event
type is of truncate operation currently file metadata is not reloaded.
This patch addresses this issue, where the alter table event type is
verified if it's a truncate operation and then reload the file metadata
accordingly.
Note: Alter table event for an external table generated by the truncate
operation from Impala cannot be identified if it's a truncate op or not
This becomes an issue in multi cluster Impala environments where events
generated from one impala cluster is consumed by other impala clusters.
Truncate operations in Impala on replicated tables will generated alter
event with 'isTruncateOp' field set to true.
Testing:
Added an end-to-end test to verify whether file metadata is reloaded
for the above scenario.
