Description

When we deal with off heap cells we will end up copying Cell components on heap

public void write(Cell cell) throws IOException {
.................
      write(cell.getRowArray(), cell.getRowOffset(), cell.getRowLength(), compression.rowDict);
      write(cell.getFamilyArray(), cell.getFamilyOffset(), cell.getFamilyLength(),
          compression.familyDict);
      write(cell.getQualifierArray(), cell.getQualifierOffset(), cell.getQualifierLength(),
          compression.qualifierDict);
......
      out.write(cell.getValueArray(), cell.getValueOffset(), cell.getValueLength());
...

We need to avoid this.
