https://github.com/apache/incubator-carbondata/pull/872 [CARBONDATA-1007] Keep the pointers in unsafe to reduce the GC over head
Current unsafe sort does not keep pointers in memory. Memory profiler shows considerable amount of java heap taken by row pointers.
So this PR keeps pointers to offheap to reduce GC over head
