[jira] [Created] (IMPALA-9843) Add ability to run schematool

------------------------------------
Summary: Add ability to run schematool against HMS in minicluster
Key: IMPALA-9843
URL: https://issues.apache.org/jira/browse/IMPALA-9843
Project: IMPALA
Issue Type: Improvement
Reporter: Sahil Takiar
When the CDP version is bumped, we often need to re-format the HMS postgres database because the HMS schema needs updating. Hive provides a standalone tool for performing schema updates: [https://cwiki.apache.org/confluence/display/Hive/Hive+Schema+Tool]
Impala should be able to integrate with this tool, so that developers don't have to blow away their HMS database every time the CDP version is bumped up. Even worse, blowing away the HMS data requires performing a full data load.
It would be great to have a wrapper around the schematool that can easily be invoked by developers.
