Zhongshuai Pei commented on SPARK-9725:
---------------------------------------
In my environment,"offset" did not change according to BYTE_ARRAY_OFFSET.
when set spark.executor.memory=36g, "BYTE_ARRAY_OFFSET" is 24, "offset" is 16 ,
but set spark.executor.memory=30g, "BYTE_ARRAY_OFFSET" is 16, "offset" is 16
too. So "if (offset == BYTE_ARRAY_OFFSET && base instanceof byte[] &&
((byte[]) base).length == numBytes)" will get different result. [~rxin]
