Method equalByteArrays

src/org/apache/pig/data/DataType.java:1634–1650

Test whether two byte arrays (Java byte arrays not Pig byte arrays) are equal. I have no idea why we have this function. @param lhs byte array 1 @param rhs byte array 2 @return true if both are null or the two are the same length and have the same bytes.

(byte[] lhs, byte[] rhs)

     * the same bytes.

            return true;
        }
        if(lhs == null || rhs == null) {
