We've applied the patch (along with HIVE-9083) and it seems to be working as expected. I just wanted to validate (to whatever extent possible) that the patch syntax is going to be the syntax going forward before we update our scripts.

FWIW, I prefer the syntax from the patch. I think it reads more cleanly. Agreed, DROP PURGE PARTITION is harder to understand than DROP PARTITION PURGE. The IF EXISTS option doesn't have the same natural language problem. But it's confusing to put PURGE after PARTITION in the ALTER statement (separate from IF EXISTS) while the DROP TABLE statement puts it next to IF EXISTS. * Would the DROP TABLE syntax be better if it were DROP TABLE IF EXISTS table_name PURGE? But that breaks backward compatibility (PURGE was added in 0.14.0). * Should the syntax of both statements be changed to tolerate either placement of PURGE?

Mithun Radhakrishnan commented on HIVE-9086:
Judging from [the
patch|https://issues.apache.org/jira/secure/attachment/12670435/HIVE-7100.11.patch#file-12],
HIVE-7100 added the drop-table-purge functionality to read thus:
{code:sql}
DROP TABLE IF EXISTS my_doomed_table PURGE;
{code}
The current alter table drop partitions reads as follows:
{code:sql}
ALTER TABLE my_doomed_table DROP IF EXISTS PARTITION (part_key = sayonara)
IGNORE PROTECTION;
{code}
HIVE-9086 extends HIVE-7100's purge-functionality to partitions, and suggests
that the {{PURGE}} keyword go at the end, thus:
{code:sql}
ALTER TABLE my_doomed_table DROP IF EXISTS PARTITION (part_key = sayonara)
IGNORE PROTECTION PURGE;
{code}
Should {{PURGE}} sit before/after {{IF EXISTS}} or after {{IGNORE PROTECTION}}?
We can't break backward compatibility, so we shouldn't be changing what we
released in 0.14.
Add language support to PURGE data while dropping partitions.
