Robert Joseph Evans updated MAPREDUCE-3501:
-------------------------------------------
Component/s: mrv2
> Fifo scheduler does not match host requests with host:port correctly
> --------------------------------------------------------------------
>
> Key: MAPREDUCE-3501
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3501
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2, scheduler
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Robert Joseph Evans
> Priority: Minor
>
> When the Fifo scheduler receives a heartbeat from a NM the NM appears as a
> HOST:PORT. When a request is made to the scheduler to have a container run
> on a given host that request is given just as HOST. Right now the FIFO
> scheduler does not use just the HOST part of HOST:PORT for the comparison.
> This is minor because very few people will run with the FIFO scheduler on a
> cluster at all, but it still needs ot be fixed.
