Subject Re: Problem with running the job, no default queue
Date Sun, 20 Feb 2011 23:32:35 GMT
Hello Koji,

Thanks for your email. Is there a M45 specific mailing list. That would be really beneficial.

I tried the hadoop queue command
and it gives me

Queue acls for user :  sgrao

Queue  Operations
=====================
m45  submit-job

need I specify this queue name in my properties? or modify the mapred-queue-acls.xml file.
I do not think I have the authorization to do so.

I even ran a info on the queue name I found "m45"

$hadoop queue -info m45
Queue Name : m45
Scheduling Info : Queue configuration
Capacity Percentage: 90.0%
User Limit: 20%
Priority Supported: NO
-------------
Map tasks
Capacity: 684 slots
Used capacity: 400 (58.5% of Capacity)
Running tasks: 200
Active users:
User 'scohen': 400 (100.0% of used capacity)
-------------
Reduce tasks
Capacity: 342 slots
Used capacity: 5 (1.5% of Capacity)
Running tasks: 5
Active users:
User 'ukang': 5 (100.0% of used capacity)
-------------
Job info
Number of Waiting Jobs: 2
Number of users who have submitted jobs: 2

How do I request for a queue. I tried adding -Dmapred.queue.name to the end of the hadoop
command

hadoop jar /grid/0/gs/hadoop/current/hadoop-examples.jar pi 10 10000 -Dmapred.queue.name=m45

It gives me a usage error, as if I cannot specify the queue or I am using the wrong syntax.
I have not been able to find the right syntax.

So I am not sure how to specify the queue name or request for a queue.

Regards,
Shivani

Hi Shivani, 

You probably don’t want to ask m45 specific questions on hadoop.apache mailing list. 

Try 

% hadoop queue –showacls 

It should show which queues you’re allowed to submit. If it doesn’t give you any queues,
you need to request one.

Tried a simple example job with Yahoo M45. The job fails for non-existence of a default queue.

Output is attached as below. From the Apache hadoop mailing list, found this post (specific
to M45), that attacked this problem by setting the property Dmapred.job.queue.name=*myqueue*
( http://web.archiveorange.com/archive/v/3inw3ySGHmNRR9Bm14Uv ) 

There is also documentation set for capacity schedulers, but I do not have write access to
the files in conf directory, so I do not know how I can set the capacity schedulers there.


I am also posting this question on the general lists, just in case.
