Why pig depends on job history server ?

I hit the issue as the following link, seems restarting job history server
can fix the issue. But I am just confused why pig would depend on job
history server. Anyone know that ? Thanks

Hi,

I think this is how Pig gets information on the MR job.
Here Pig wants to get statistical information - counters (e.g. how many
bytes were read/written during MR job execution) from the remote server
(providing the jobID)

Regards,
Adam
