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.
