[jira] [Commented] (HIVE-3264) Add support for binary dataype to AvroSerde

["Eli Reisman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13426909#comment-13426909 ] 

Eli Reisman commented on HIVE-3264:
-----------------------------------

Looking at the source, I'm seeing AvroSerDe code mapping BYTE to Constants.TINYINT_TYPE_NAME in Hive, but binary type (array/blob) already maps to Constants.BINARY_TYPE_NAME -- and inside the Hive constants, I see no "byte" type to replace TINYINT_TYPE_NAME, is there something I'm missing? I could not tell from the description whether the binary type is what you were discussing (looks like its already in place), or the single-byte type in specific. In that case, there is no replacement I can find for  tiny int on the Hive side. I didn't see anything on the binary array being implemented as tiny ints any more in the code. I am looking in the org.apache.hive.serde2.* packages.

> When the AvroSerde was written, Hive didn't have a binary type, so Avro's byte array type is converted an array of small ints.  Now that HIVE-2380 is in, this step isn't necessary and we can convert both Avro's bytes type and probably fixed type to Hive's binary type.
