lt looks like your task took a long time to complete (> 10 minutes) and didn't produce any output or report any status to Hadoop during this time.
This often happens during indexing tasks where a reducer or mapper builds some off-line data structure for a long time. Can you force your mappers to update a Hadoop counter as they go along? That might be all that is needed. On Tue, Dec 7, 2010 at 5:37 AM, rajgopalv <[email protected]> wrote: > Task attempt_201012071646_0001_m_000025_0 failed to report status for 600 > seconds.
