--------------------------------
> Make some collect stats flags be user configurable
> --------------------------------------------------
>
> Key: HIVE-20246
> URL: https://issues.apache.org/jira/browse/HIVE-20246
> Project: Hive
> Issue Type: Improvement
> Components: Metastore
> Reporter: Alice Fan
> Assignee: Alice Fan
> Priority: Minor
> Fix For: 4.0.0
>
>
> When hive.stats.autogather=true then the Metastore lists all files under the
> table directory to populate basic stats like file counts and sizes. This file
> listing operation can be very expensive particularly on filesystems like S3.
> One way to address this issue is to reconfigure hive.stats.autogather=false.
> However, set metaconf:hive.stats.autogather=false will not be taken by
> HiveMetaStore when user set this in session.
