HMS metadata will > also be reloaded every time, which is an unnecessary overhead (and potential > point of failure) when adding files to existing locations. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
