-----------------------------------
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.
