> This is because HBase input format is stateful. When there are concurrent
> queries running, same HBase input format is reused by multiple threads. When
> one thread closes HBase connection, the other thread that wants to fetch data
> from HBase can not submit task to HTable's ThreadPoolExecutor because the
> HBase connection is closed and ThreadPoolExecutor is shutdown.
>
> Caching of HBase input format is disabled in HiveInputFormat as part of
> HIVE-8808. Same fix needs to be applied in FetchOperator.
