Wenxin He commented on YARN-6873: --------------------------------- Verified +1: I added {{EWMA}} to {{log4j.rootLogger}} in log4j.properties {noformat} log4j.rootLogger=${hadoop.root.logger}, EventCounter, EWMA {noformat} , restarted ApplicationHistoryServer and found "Errors/Warnings" link in the web http://<ApplicationHistoryServer address>:8188/applicationhistory. BTW: The issue we broke in [^YARN-6873.003.patch] may not be YARN-2901. YARN-3511 introduced the code that we broke, am I right? > Moving logging APIs over to slf4j in > hadoop-yarn-server-applicationhistoryservice > --------------------------------------------------------------------------------- > > Key: YARN-6873 > URL: https://issues.apache.org/jira/browse/YARN-6873 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Yeliang Cang > Assignee: Yeliang Cang > Attachments: YARN-6873.001.patch, YARN-6873.002.patch, > YARN-6873.003.patch, YARN-6873.004.patch > > -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
