compatibility between hive and spark)
> Add a warning for Hive 2.1.1 ORC reader issue
> ---------------------------------------------
>
> Key: SPARK-26932
> URL: https://issues.apache.org/jira/browse/SPARK-26932
> Project: Spark
> Issue Type: Documentation
> Components: Documentation
> Affects Versions: 2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.4.0
> Reporter: Bo Hai
> Priority: Minor
>
> As of Spark 2.3 and Hive 2.3, both supports using apache/orc as orc writer
> and reader. In older version of Hive, orc reader(isn't forward-compitaient)
> implemented by its own.
> So Hive 2.2 and older can not read orc table created by spark 2.3 and newer
> which using apache/orc instead of Hive orc.
> I think we should add these information into Spark2.4 orc configuration file
> : https://spark.apache.org/docs/2.4.0/sql-data-sources-orc.html
