Yeliang Cang commented on YARN-7243: ------------------------------------ In the below code: {code:title=FairSchedulerEventLog.java} synchronized void log(String eventType, Object... params) { try { if (logDisabled) return; StringBuffer buffer = new StringBuffer(); buffer.append(eventType); for (Object param: params) { buffer.append("\t"); buffer.append(param); } String message = buffer.toString(); Logger logger = Logger.getLogger(getClass()); appender.append(new LoggingEvent("", logger, Level.INFO, message, null)); } catch (Exception e) { LOG.error("Failed to append to fair scheduler event log", e); logDisabled = true; } } {code} The variable "logger" in method LoggingEvent is an object of org.apache.log4j.Category. I don't know how to deal with it, so I just leave it unchanged. Also, org.apache.log4j.LogManager is used in testRM.java and many other UT files. I leave them unchanged, too! > Moving logging APIs over to slf4j in hadoop-yarn-server-resourcemanager > ----------------------------------------------------------------------- > > Key: YARN-7243 > URL: https://issues.apache.org/jira/browse/YARN-7243 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Yeliang Cang > Assignee: Yeliang Cang > Attachments: YARN-7243.001.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
