Subject [jira] [Created] (GIRAPH-23) Giraph causes capacity scheduler to report crazy statistics

Giraph causes capacity scheduler to report crazy statistics
-----------------------------------------------------------

                 Key: GIRAPH-23
                 URL: https://issues.apache.org/jira/browse/GIRAPH-23
             Project: Giraph
          Issue Type: Bug
         Environment: Hadoop 20.2, non-secure with capacity scheduler
            Reporter: Jakob Homan


Not sure why, but all our Giraph jobs create crazy values for the scheduler in terms of number
of mappers:
{noformat}51 running map tasks using -52224 map slots, 0 running reduce tasks using 0 reduce
slots. {noformat}
and this trickles out to the whole cluster:
{noformat}Used capacity: -58229 (-12468.7% of Capacity){noformat}
These numbers don't appear to affect the job and the correct themselves a short time after
the Giraph job finishes running.
