Setting the job tracker node
Different 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
$ 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.
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.
