-------------------------------------
Summary: AM hung with one pending map task
Key: MAPREDUCE-4982
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4982
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mr-am
Affects Versions: 2.0.3-alpha, 0.23.6
Reporter: Jason Lowe
Saw a job that hung with one pending map task that never ran. The task was in
the SCHEDULED state with a single attempt that was in the UNASSIGNED state.
The AM looked like it was waiting for a container from the RM, but the RM was
never granting it the one container it needed.
I suspect the AM botched the container request bookkeeping somehow. More
details to follow.
