Description

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.
