Behaviour with AHS with file based history store
        -Apphistory url is working 
        -No attempt entries are shown for each application.
        

Based on inital analysis when RM switches ,application attempts from state 
store  are not replayed but only applications are.
So when /applicaitonhistory url is accessed it tries for all attempt id and 
fails
