Subject [jira] Created: (HADOOP-6099) Allow configuring the IPC module to send pings
Date Tue, 23 Jun 2009 09:14:07 GMT
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.
