-----------------------------

this patch is no longer required, as PIG-954 contains the fix for this.

> Default value of memusage for skewed join is not correct

> Fragmented replicated join has a few limitations:
>  - One of the tables needs to be loaded into memory
>  - Join is limited to two tables
> Skewed join partitions the table and joins the records in the reduce phase. 
> It computes a histogram of the key space to account for skewing in the input 
> records. Further, it adjusts the number of reducers depending on the key 
> distribution.
> We need to implement the skewed join in pig.
