> URL: https://issues.apache.org/jira/browse/SPARK-17063
> Project: Spark

> Fix For: 2.0.1, 2.1.0
>
>
> When repair a table with thousands of partitions, it could take hundreds of
> seconds, Hive metastore can only add a few partitioins per seconds, because
> it will list all the files for each partition to gather the fast stats
> (number of files, total size of files).
> We could improve this by listing the files in Spark in parallel, than sending
> the fast stats to Hive metastore to avoid this sequential listing.
