Sriranjan Manjunath updated PIG-962:
------------------------------------
Description: The first job is a load / store job which loads the data from
PigStorage and stores it in BinStorage. This hampers performance. The desired
behavior is for the sampler to read from PigStorage instead of relying on the
first load/store job. Skewed join should thus be 2 M/R jobs and not 3. (was:
