[CARBONDATA-3835] Fix global sort issues Why is this PR needed? For global sort without partition, string comes as byte[], if we use string comparator (StringSerializableComparator) it will convert byte[] to toString which gives address and comparison goes wrong. For global sort with partition, when sort column is partition column, it was sorting on first column instead of partition columns. What changes were proposed in this PR? change data type to byte before choosing a comparator. get the sorted column based on index, don't just take from first Does this PR introduce any user interface change? No Is any new testcase added? Yes This closes #3779
