Major Description
HCatLoader reuses credentials of stage1 in stage2 for some of the pig queries. This causes stage-2 to fail, if stage-2 runs for more than 10 mins. Pig queries which loads data using HCatLoader, filters only by partition columns and does an order by will run into this problem. Exceptions will be very similar to the following:
