-------------------------------------------------------------
The operation log is deleted at once on operation closing(except for canceling
operation), so there probably have no chance to get the operation log after
operation finished/failed except searching through the whole log file. It
sometimes becomes a problem for async operations and parallel executing tasks.
In order to get the log of a finished/failed query for diagnosing, maybe we
should keep the operation log alone for some time after the query is finished.

{quote}I would rather implement something like HIVE-24574.

> Currently we provide getQueryLog in HiveStatement to fetch the operation log,
> and the operation log would be deleted on operation closing(delay for the
> canceled operation). Sometimes it's would be not easy for the user(jdbc) or
> administrators to deep into the details of the finished(failed) operation, so
> we present the operation log on webui and keep the operation log for some
> time for latter analysis.
