URL: https://github.com/apache/carbondata/pull/3172
 
 
   **Problem:** When vector filter push down is true and the table contains a null value then thegetNullBitSet method is giving an byte[]to represent null. But there is no check for the value of the bitset.
   
   **Solution:** Check if null bit set length is 0 then set the same to the chunkData.
