Hi All,

I am trying to upgrade MapR 3.1 to MapR 4.1.
In MapR 3.1 i am starting jobtracker and tasktracker using warden.Warden configuration is like
service.command.jt.start=hadoop-daemon.sh start jobtracker
service.command.tt.start=hadoop-daemon.sh start tasktracker

In MapR 4.1 i am trying to configure in same way but the output of this command is :

DEPRECATED: Use of this script to execute mapred command is deprecated.
Instead use the mapred command for it.

Sorry, the jobtracker command is no longer supported.
You may find similar functionality with the "yarn" shell command.
Usage: mapred [--config confdir] COMMAND
       where COMMAND is one of:
  pipes                run a Pipes job
  job                  manipulate MapReduce jobs
  queue                get information regarding JobQueues

So how can i configure jobtracker in tasktrcker in MapR 4.1

Thanks,
Sumit
