Alice Fan reassigned HIVE-20246: -------------------------------- > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
