> {color:#FF0000}*Hadoop Pipes Ping implement has a bug*{color}. Recently, we
> upgrade linux kernel version from 3.x to 4.x. And we find hadoop pipe task
> exit with connect timeout which is implemented by PingThread in
> HadoopPipes.cc.
> !image-2021-03-15-14-37-32-184.png!
> After a deep research, we finally find that current ping server won't accept
> ping client created socket, which may cause critical problem:
> * it will cause tcp accept queue full(default 50)
> * when client close socket, server socket won't call close method, which
> will leave too many CLOSE_WAIT socket fd existed(default 2h), and accept
> queue never cleared.
> * Even worse, in 4.x linux kernel version, it will cause tcp drop packet
> directly which makes ping client connect time out. While In 3.x linux kernel
> version, when accept queue full, client can also make half connection till
> sync queue full (default 2048), so from client side, ping will aslo work till
> sync queue full. And after 3 hours, task will also exit with connect timeout
> exception.
> To fix this bug, we introduced a PingSocketCleaner thread, which will
> continuously accept ping socket connect from ping client. When socket close
> from client, cleaner thread will detecte closed inputStream reading, then
> finally close socket from sever side.
> Refrenced by linux kernel patch:
> [https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5ea8ea2cb7]
