Hi, Sorry for asking too many questions. :)
I have created my own Metrics2 sink and only deploy it to NodeManager node, so it has name as "hadoop-metrics2-nodemanager.properties", it seems I cannot get help from Ambari to distribute them to NM nodes, thought it's not a big deal, where my property file will be? /etc/hadoop/conf or /usr/lib/hadoop-yarn/etc/hadoop/? -- --Anfernee
