https://github.com/apache/spark/pull/9853
[SPARK-11865] [network] Avoid returning inactive client in
TransportClientFactory.
There's a very narrow race here where it would be possible for the timeout
handler
to close a channel after the client factory verified that the channel was
still
active. This change makes sure the client is marked as being recently in
use so
that the timeout handler does not close it until a new timeout cycle
elapses.
