    Description

      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.
