[jira] [Commented] (HIVE-8224) Support Char, Varchar in AvroSerDe

["Lefty Leverenz (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-8224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14174791#comment-14174791 ] 

Lefty Leverenz commented on HIVE-8224:
--------------------------------------

Doc note:  This should be documented in the AvroSerDe wikidoc.  It's not as simple as adding a version note in one place, because there are several CREATE TABLE examples that supposedly include all data types.

So consider changes to these sections:

* [AvroSerDe -- Avro to Hive type conversion | https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-AvrotoHivetypeconversion]
* [AvroSerDe -- Creating Avro-backed Hive tables -- Hive 0.14 and later versions | https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-Hive0.14andlaterversions] (if add char & varchar to the example, point out that they weren't included in the previous example for all Hive versions)
* [AvroSerDe -- Writing tables to Avro files -- Example | https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-Example] ("the following Hive table, which covers all types of Hive data types" needs to be rewritten)
* [AvroSerDe -- Writing tables to Avro files -- Hive 0.14 and later | https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-Hive0.14andlater] (uses the same example as pre-0.14, so shouldn't include char & varchar but they could be mentioned here)
