Hadoop 2.2.0 jobtracker is not starting

Question

It seems I have no jobtracker with Hadoop 2.2.0. JPS does not show it, there is no one listening on port 50030, and there are no logs about the jobtracker inside the logs folder. Is this because of YARN? How can I configure and start the job tracker?

Answer 1

If you are using YARN framework, there is no jobtracker in it. Its functionality is split and replaced by ResourceManager and ApplicationMaster. Here is expected jps prinout while running YARN

$jps
18509 Jps
17107 NameNode
17170 DataNode
17252 ResourceManager
17309 NodeManager
17626 JobHistoryServer
