@Deprecated public interface JobTracker extends DistributedObject
The JobTracker interface is used to create instances of
on the given data structure / data source.
The default usage is same for both cases and looks similar to the following example:
HazelcastInstance hz = getHazelcastInstance(); IMap map = hz.getMap( getMapName() ); JobTracker tracker = hz.getJobTracker( "default" ); Job job = tracker.newJob( KeyValueSource.fromMap( map ) );
The created instance of JobTracker is fully threadsafe and can be used concurrently and multiple times.
Caution: Do not use the JobTracker with data structures of other
instances than the one used for creation of the JobTracker. Unexpected results may happen!
