[jira] [Commented] (SPARK-18482) make sure Spark can access the table metadata created by older version of spark

    [ https://issues.apache.org/jira/browse/SPARK-18482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15691450#comment-15691450 ] 

Reynold Xin commented on SPARK-18482:
-------------------------------------

What's the deal with this? Can we just dump the table metadata created by Spark 2.0, and put it in a test case and try to read it back in Spark 2.1?

> In Spark 2.1, the way of storing table metadata into Hive metastore has been changed a lot. e.g. no runtime schema inference, store partition columns, store schema for hive tables, etc. We should add compatibility tests for them
