Benoit Perroud updated HADOOP-16728:
------------------------------------
Description:
This issue is trying to address few issues in the SFTP filesystem, and
especially in SFTPConnectionPool:
* all channels for a given connectionInfo are removed from the pool instead of
only the selected channel.
*
As a result, if you have 2 threads sharing the pool, the first one acquiring a
channels removes all the others, leading to inefficient SSH reconnections.
