--------------------------------
Summary: 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
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.
