If you see
input[i++]= "0\t\t\t\t\t\t"; //Empty values except first column
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.
