Subject [jira] [Created] (MAPREDUCE-3501) Fifo scheduler does not match host requests with host:port correctly
Date Fri, 02 Dec 2011 15:45:40 GMT
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: 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.
