---------------------------------------
[~szita]: Sorry for reply a bit late.

This can be seen by just repeating the same pig query, (e.g. load, foreach,
dump, dump) - the second job will hang in SparkStatsUtil#waitForJobAddStats.
Reason is that JobGraphBuilder#getJobIDs will return all jobs accociated with
the same groupID, in the case above 0 and 1. Then it will wait for job 0 to
finish but that's no longer in sparkContext, it was the previous job..

not very understand. use following repeating query(load) script and run
successfully.
{code}
A = load './SkewedJoinInput1.txt' as (id,name,n);
B = load './SkewedJoinInput1.txt' as (id,name);
store A into './duplicate.out.A';
store B into './duplicate.out.B';
explain A;
{code}
Can you give a script to show the failure you mentioned above?

> currently, we initialize MRConfiguration.JOB_ID in SparkUtil#newJobConf.
> we just set the value as a random string.
> {code}
> jobConf.set(MRConfiguration.JOB_ID, UUID.randomUUID().toString());
> {code}
> We need to find a spark api to initiliaze it correctly.
