Description

Currently if the value of ipc.client.rpc-timeout.ms is greater than 0, the timeout overrides the ipc.ping.interval and client will throw exception instead of sending ping when the interval is passed. RPC timeout should work without effectively disabling IPC ping.

• breaks: HDFS-9946 MiniDFS clusters failing to come up, "timeout can't be negative"
• is duplicated by: HADOOP-14262 rpcTimeOut is not set up correctly in Client thus client doesn't time out
• is related to: HADOOP-11252 RPC client does not time out by default
• is related to: HADOOP-14926 Reconsider the default value of RPC timeout and document it
• requires: HDFS-9954 Test RPC timeout fix of HADOOP-12672 against HDFS
