bq. If you see
bq. input[i++]= "0\t\t\t\t\t\t"; //Empty values except first column
bq. already has empty value for the binary field f. The problem is pig
stores a empty byte array when there is a empty value for a bytearray column
but null for all other data types. Only way to store null in a bytearray column
using pig was to not make it not part of the pig schema. So had to add another
column g which was part of hcat schema but not part of pig load schema.
okay. Makes sense. Can you add a comment mentioning the above reasoning, so
that if someone is looking at the test case it will be clear to them.
