Allow configuring the IPC module to send pings
----------------------------------------------
Key: HADOOP-6099
URL: https://issues.apache.org/jira/browse/HADOOP-6099
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Reporter: dhruba borthakur
Assignee: dhruba borthakur
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.
