Cheng Lian updated SPARK-6575:
------------------------------
Description:
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
coverting such a metastore Parquet table.
> Add configuration to disable schema merging while converting metastore
