Confusing statement for Merge Join -> Both Conditions in Pig reference manual1
------------------------------------------------------------------------------

                 Key: PIG-1848
                 URL: https://issues.apache.org/jira/browse/PIG-1848
             Project: Pig
          Issue Type: Improvement
          Components: documentation
            Reporter: Vivek Padmanabhan


In Pig reference manual , http://pig.apache.org/docs/r0.8.0/piglatin_ref1.html#Merge+Joins,
for merge join under Both Conditions ,  the example statement is confusing.

Both Conditions
For optimal performance, each part file of the left (sorted) input of the join should have
a size of at least 1 hdfs block size (for example if the hdfs block size is 128 MB, each part
file should be less than 128 MB).
