[jira] [Created] (HIVE-10657) Remove copyBytes operation from MD5 UDF

Alexander Pivovarov created HIVE-10657:
------------------------------------------

             Summary: Remove copyBytes operation from MD5 UDF
                 Key: HIVE-10657
                 URL: https://issues.apache.org/jira/browse/HIVE-10657
             Project: Hive
          Issue Type: Improvement
          Components: UDF
            Reporter: Alexander Pivovarov
            Assignee: Alexander Pivovarov
            Priority: Minor


Current implementation uses Apache Commons  DigestUtils.md5Hex method to get md5 hex.
DigestUtils does not provide md5Hex method with signature (byte[], start, length). This is why copyBytes method was added to get bytes[] from BytesWritable.

To avoid copying bytes from BytesWritable to new byte array we can use java MessageDigest API directly.
MessageDigest has method update(byte[], start, length)
