> (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)
