-------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-3276
                 URL: https://issues.apache.org/jira/browse/HADOOP-3276

    Affects Versions: 0.17.0
            Reporter: Karam Singh
            Priority: Minor


Allocated cluster using hod of 5 nodes . It returned the both Mapred and Hdfs UI addresses.
Also checked out of nodes on 3 taskterakers nodes were using getTaskTrackers() api. 
Then tried to run wordcount example and got following -:
org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.mapred.JobTracker$IllegalStateException:

(Here dfs was static with permissions on.)
On further checking there was problem in static dfs setting, but Web UI was getting started
resulting successful allocation, but was not able create mparedsystem directory causing JobTracker$IllegalStateException.
So, It seems if Web UI up then hod assumes that Mapred JT is running
(This is rare condition)
