[jira] Created: (HADOOP-540) Streaming should send keep-alive signals to Reporter

Streaming should send keep-alive signals to Reporter
----------------------------------------------------

                 Key: HADOOP-540
                 URL: http://issues.apache.org/jira/browse/HADOOP-540
             Project: Hadoop
          Issue Type: Bug
          Components: contrib/streaming
            Reporter: Michel Tourn


The goal is to avoid the 10-minutes Task timeout with certain usages of hadoopStreaming.

This proposal does not introduce an artificial keep-alive heartbeat: 
it still requires the external Application to have activity.

Streaming should set Reporter status in more places:

1. output to side-effect files should (periodically) set reporter status.

2. Application's stderr data should (periodically) set reporter status.
