I am trying to get the job tracker counters in my reducer. It works on
single node demo hadoop but fails on a real cluster where kerberos is used
for authentication.
********************************************
RunningJob parentJob =
client.getJob(JobID.forName(
context.getConfiguration().get("mapred.job.id") ));
Counters counters = parentJob.getCounters();
********************************************
The call to getCounter() API throws GSSException (No valid credentials
provided - Failed to find any kerberos tgt).
I launched this job using hadoop jar command.
Any help would be much appreciated.
Thanks
Manish
