Running pig script gives the error as: job has failed. Stop running all dependent jobs - hadoop

Question

I need a help in why I am getting an error while running a pig script. But when I try the same script in a smaller data, it executes successfully.
There are a few questions with similar issues, but none of them have the solution.
My script looks like this:
A = load ‘test.txt’ using TextLoader();
B = foreach A generate STRSPLIT($0,’”,”’) as t;
C = FILTER B BY (t.$1==2 and t.$2 matches ‘.*xxx.*’);
Store C into temp;
The error is:

Any help will be appreciated.
Thanks.

Answer 1

After some research, I found that the problem here is LeaseExpiredException. This might be because the output of mapper was removed. One of the reason for this might be due to the quota allocated for the user. In my case, I was running this script in a very large data, and my quota was insufficient to process/store the data.
We can check the quota by the following command:
hadoop fs -count -q /user/username
Thank you.
