Yin Huai reopened SPARK-6575:
-----------------------------
> Add configuration to disable schema merging while converting metastore
> Parquet tables
> -------------------------------------------------------------------------------------
>
> Key: SPARK-6575
> URL: https://issues.apache.org/jira/browse/SPARK-6575
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
> Priority: Blocker
> Fix For: 1.3.1, 1.4.0
>
>
> Consider a metastore Parquet table that
> # doesn't have schema evolution issue
> # has lots of data files and/or partitions
> In this case, driver schema merging can be both slow and unnecessary. Would
> be good to have a configuration to let the use disable schema merging when
> converting such a metastore Parquet table.
