Eugene Chung created HIVE-23458: ----------------------------------- Summary: Introduce unified thread pool for scheduled jobs Key: HIVE-23458 URL: https://issues.apache.org/jira/browse/HIVE-23458 Project: Hive Issue Type: Improvement Components: HiveServer2 Reporter: Eugene Chung Assignee: Eugene Chung
As I mentioned in [the comment of HIVE-23164|https://issues.apache.org/jira/browse/HIVE-23164?focusedCommentId=17089506&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17089506], I've made the unified scheduled executor service like org.apache.hadoop.hive.metastore.ThreadPool. I think it could help 1. to minimize the possibility of making non-daemon threads when developers need ScheduledExecutorService 2. to achieve the utilization of server resources because the current situation is all of the modules make its own ScheduledExecutorService and all of the threads are just using for one job. 3. an administrator of Hive server by providing hive.exec.scheduler.num.threads configuration. -- This message was sent by Atlassian Jira (v8.3.4#803005)
