long time and the speculative execution does not kick in
Reduce task stuck at 95.71% for a long time and the speculative execution does not kick in
------------------------------------------------------------------------------------------
Key: HADOOP-2933
URL: https://issues.apache.org/jira/browse/HADOOP-2933
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Affects Versions: 0.16.0
Reporter: Runping Qi
I have a job with speculative execution set on.
However, its last reduce task has been stuck for a long time at 95.71%, and no speculative execution was started.
I did see speculative executions for other tasks started and killed though.

Seems like this issue related to HADOOP-2177. Should I close this?
