Re: Help with PIG 0.7 and JOINs
You would find the log for MR jobs that failed either at -
http://srwaishdc1jn0001:50030/jobdetails.jsp?jobid=job_201007221306_7120
Or
http://srwaishdc1jn0001:50030/jobdetails.jsp?jobid=job_201007221306_7119

You can forward the error message if you need further help with this.

Hi Guys,

I am trying to do join tow data sets and the jobs are failing. There are
some warnings reported and I am not good at understanding them. I am seeking
your help in adjusting any parameters to the job so that the job might
succeed.

Here is the grunt shell output:

grunt> STORE fjid INTO '/apps/sq/ryakkala/trec_fixed_price_0820_us_clicks'
