Setting the job tracker node

Different ways to set the job tracker node.

There are several ways to set the job tracker node.
  • You can start up an analytics node using the -j option on a tarball installation. This option designates the node being started as the job tracker node.
    $ install_location/bin/dse cassandra -t -j

    You can also use this method on a packaged installation to designate the job tracker when starting the analytics node as a standalone process instead of a service.

  • You can use the dsetool movejt command.

About the reserve job tracker 

DataStax Enterprise nominates a node in the cluster as a reserve job tracker for a data center. The reserve job tracker becomes the job tracker when, for some reason, there is no local node in the data center that can function as job tracker.
