-----------------------------------------------------------------------
Key: MAPREDUCE-708
URL: https://issues.apache.org/jira/browse/MAPREDUCE-708
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.20.1
Reporter: Ramya R
Priority: Minor
Fix For: 0.20.1
After MAPREDUCE-211, the node health check script does not refresh the "reason
for blacklisting".
The steps to reproduce the issue are:
* Blacklist a TT with an error message 'x'
* Change the health check script to return an error message 'y'
* The "reason for blacklisting" still shows 'x'
The impact of this issue is that the feature fails to trap transient errors.
