Some Problems!

[liuwwei3]

(i). JobClient throws an IoException! "The Client is stopped!"

After calling:
JobClient.runJob()
to start a hadoop job , it throws an error ("IoException: The Client is stopped") while calling
job .getCounters()
subsquently.

It is ok to use:
JobClient jobclient = new JobClient(conf);
RunningJob job = jobclient.submitJob(conf);
job.waitForCompletion();
(ii). counters.findCounter(x, y) takes at least two params, there only one param in your code.

in fact, it is not necessary to call 'findCounter',
XXX = counters.getCounter(MyCounter.LEFT_OVER_TERMS);
is just fine!
