Setting queue name in pig v0.15 - hadoop

Question

I am getting below exception while trying to execute pig script via shell.
JobId Alias Feature Message Outputs
job_1520637789949_340250 A,B,D,top_rec GROUP_BY Message: java.io.IOException: org.apache.hadoop.yarn.exceptions.YarnException: Failed to submit application_1520637789949_340250 to YARN : Application rejected by queue placement policy
I understand that it is due to not setting the correct queue name for MR execution. In order to find that how to set a queuename for mapreduce job, I tried searching thorough help, pig --help, it listed below options

18/03/30 13:03:05 INFO pig.Main: Pig script completed in 163 milliseconds (163 ms)
I tried pig -p mapreduce.job.queuename=my_queue; and was able to login into grunt without any error.
However, on the first command itself, it threw below
ERROR 2997: Encountered IOException. org.apache.pig.tools.parameters.ParseException: Encountered " <OTHER> ".job.queuename=my_queue "" at line 1, column 10.
Was expecting:
"=" ...
I am not sure, if I am doing it right?

Answer 1

To set queuename in pig 0.15, I got below options (it may works for other version too):
1) pig comes with an option to start the pig session using a queue name.
Simple use below commands
pig -Dmapreduce.job.queuename=my_queue
2) Another option is to set the same in the grunt shell or in the pig script itself.
set mapreduce.job.queuename my_queue;
