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 -:

(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)
