Mohit Sabharwal commented on HIVE-12431:
----------------------------------------
When global (HS2-wide) compile lock is configured, a long-compiling request
will block remaining sessions indefinitely.
Attached patch allows the user to configure the maximum time a request will
wait to acquire the compile lock. Note that this configuration does not apply
when session scoped compile locking is configured.
> Support timeout for global compile lock

> 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.
