Konstantin Shvachko commented on HADOOP-6099:
---------------------------------------------
I see. So you want to be able to set
ipc.client.ping = false - no ping, and at the same time
ipc.ping.interval = 20, which is now treated not as ping interva because there
are no pingsl, but as a client timeout.
> Allow configuring the IPC module to send pings

> The IPC Client sets a socketTimeout for the time period specified by the
> pingInterval and then sends a ping every pingInterval. This means that if a
> RPC server does not respond to a RPC client, then the RPC client blocks
> forever. This is a problem for applications that wants to switch quickly from
> one un-responsive HDFS cluster to a good one.
