Arun C Murthy commented on MAPREDUCE-682:
-----------------------------------------
While we are at it, we should ensure that nodes declared unhealthy
(MAPREDUCE-211) also are removed from the list of reserved tasktrackers for
jobs...
> Reserved tasktrackers should be removed when a node is globally blacklisted

> Key: MAPREDUCE-682
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-682
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker
> Affects Versions: 0.21.0
> Reporter: Hemanth Yamijala
>
> When support was added to reserve tasktrackers for high RAM jobs per
> MAPREDUCE-516, we missed removing reservations on tasktrackers that are
> globally blacklisted. This is not a major concern, just that the reservation
> might cause the job to finish a little later than if the reservation is
> removed when the blacklisting happens.
