Ajantha Bhat updated CARBONDATA-3835:
-------------------------------------
    Description:
problem:

For global sort without partition, string comes as byte[], if we  use string comparator (StringSerializableComparator) it wll convert byte[] to toString which gives address and comparision goes wrong.

 

solution: change data type to byte before choosing comparator.
