Sergey Shelukhin commented on HIVE-12431:
-----------------------------------------
Note that there's a setting now that disables the compile lock.
> Cancel queries after configurable timeout waiting on compilation

> Key: HIVE-12431
> URL: https://issues.apache.org/jira/browse/HIVE-12431
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2, Query Processor
> Affects Versions: 1.2.1
> Reporter: Lenni Kuff
>
> To help with HiveServer2 scalability, it would be useful to allow users to
> configure a timeout value for queries waiting to be compiled. If the timeout
> value is reached then the query would abort. One option to achieve this would
> be to update the compile lock to use a try-lock with the timeout value.
