[jira] [Created] (SPARK-26932) Orc compatibility between hive and spark

Bo Hai created SPARK-26932:
------------------------------

             Summary: Orc compatibility between hive and spark
                 Key: SPARK-26932
                 URL: https://issues.apache.org/jira/browse/SPARK-26932
             Project: Spark
          Issue Type: Documentation
          Components: Documentation
    Affects Versions: 2.4.0, 2.3.3, 2.3.2, 2.3.1, 2.3.0
            Reporter: Bo Hai


Since 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.

Spark2.4 orc configuration: https://spark.apache.org/docs/2.4.0/sql-data-sources-orc.html
