Rohini Palaniswamy commented on PIG-5371:
-----------------------------------------
bq. It seems like HDFS counter 'HDFS_BYTES_WRITTEN' returns the byte count not
only for the result of pig store operator, but it includes the size of the jar
files as well.
Are you sure that jar files are included in it? It is a job counter. Don't
understand how that can happen.
