Nicholas Jiang commented on FLINK-19064:
----------------------------------------
Yeah, I agree with [~jark]. From my perspective, set aside the issue scene,
other scenes need to close the HBase connection in
RichInputFormat#closeInputFormat.
And in this issue, the approach above mentioned make sense to me, but this
change would affect other cases for other connectors.
In my opinion, there is no perfect solution to solve this leaking resources
problem. [~rmetzger], do you have any great approach to handle this case?
