Thejas M Nair commented on HIVE-3246:
-------------------------------------
bq. byte [] is not a primitive. I have no issue with the change but there must
be a reason this was done. Likely a performance issue.
Yes, byte[] is not a java primitive type, but it as close as it gets to it (it
is a basic type that ships with java). ByteArrayRef is just a wrapper around
byte[], I don't see any performance advantage of using it when binary is
converted to java primitive type using the getPrimitiveJavaObject call. Fyi,
Ashutosh implemented the binary type using ByteArrayRef in HIVE-2380, I believe
he does not see a performance issue as well (based on his comment above.)
> java primitive type for binary datatype should be byte[]

> PrimitiveObjectInspector.getPrimitiveJavaObject is supposed to return a java
