If there are no other issues, could we merge in the patch? > Fix uncleaned threads in YARN Federation interceptor threadpool > --------------------------------------------------------------- > > Key: YARN-11588 > URL: https://issues.apache.org/jira/browse/YARN-11588 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Jeffrey Chang > Priority: Major > Labels: pull-request-available > > In YARN Federation a new interceptor is generated for each new user that > calls YARN Router. This also generates a threadpool which is used to call > YARN RM. However, when the call is finished the threadpool threads never > exits, causing the interceptor object for the user to never be cleaned up. > This causes an issue when the number of users is large in the YARN cluster, > as the number of idle, uncleaned thread can reach # of users calling router > times number of active core threads in thread pool. This causes performance > issues in router due to too many idle threads. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
