Hi Jagat
Thanks for your reply. I am not using Pig. I have the latest hadoop running
cloned from github trunk. Actually I was able to execute my programs until
I refreshed my github foked copy yesterday and ran a build on it. :(
I figured out from a debug that the lines that are creating a problem are:
----------------
//service to log job history events
EventHandler<JobHistoryEvent> historyService =
createJobHistoryHandler(context);
dispatcher.register(org.apache.hadoop.mapreduce.jobhistory.EventType.class,
historyService);
----------------
in the MRAppMaster.java class. The reason being the register method
from org.apache.hadoop.yarn.event.Dispatcher is not
accepting EventHandler<JobHistoryEvent> as the second argument. Not sure
why.
Regards,
Prajakta
