Support AM specific blacklisting of nodes on the RM
---------------------------------------------------
Key: MAPREDUCE-3314
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3314
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Hitesh Shah
Fix For: 0.23.1
The AM blacklists certain nodes due to task failures but the RM does not know
of this and can allocate blacklisted nodes to the AM again and again.
RM should support a protocol that allows AM to inform the RM of nodes that it
should not allocate to it.
