- - ### Uses of JobTracker in com.hazelcast.client.proxy

    Classes in com.hazelcast.client.proxy that implement JobTracker
    Modifier and Type | Class and Description
    --- | ---
    `class` | `ClientMapReduceProxy` Proxy implementation of `JobTracker` for a client initiated map reduce job.

    Methods in com.hazelcast.client.proxy with parameters of type JobTracker
    Modifier and Type | Method and Description
    --- | ---
    `<SuppliedValue,Result> Result` | ClientMultiMapProxy.`aggregate(Supplier<K,V,SuppliedValue> supplier, Aggregation<K,SuppliedValue,Result> aggregation, JobTracker jobTracker)`
    `<SuppliedValue,Result> Result` | ClientMapProxy.`aggregate(Supplier<K,V,SuppliedValue> supplier, Aggregation<K,SuppliedValue,Result> aggregation, JobTracker jobTracker)`

  - ### Uses of JobTracker in com.hazelcast.core

    Methods in com.hazelcast.core that return JobTracker
    Modifier and Type | Method and Description
    --- | ---
    `JobTracker` | HazelcastInstance.`getJobTracker(String name)` Deprecated. MapReduce is deprecated and will be removed in 4.0. For map aggregations, you can use `Aggregator` on IMap. For general data processing, it is superseded by Hazelcast Jet.

    Methods in com.hazelcast.core with parameters of type JobTracker
    Modifier and Type | Method and Description
    --- | ---
    `<SuppliedValue,Result> Result` | MultiMap.`aggregate(Supplier<K,V,SuppliedValue> supplier, Aggregation<K,SuppliedValue,Result> aggregation, JobTracker jobTracker)` Deprecated. The old Aggregations API is superseded by Fast Aggregations (`com.hazelcast.aggregation`) which does not yet support MultiMap. Hazelcast Jet can be used in the future to replace this functionality.
    `<SuppliedValue,Result> Result` | IMap.`aggregate(Supplier<K,V,SuppliedValue> supplier, Aggregation<K,SuppliedValue,Result> aggregation, JobTracker jobTracker)` Deprecated. please use fast-aggregations `IMap.aggregate(Aggregator)` or `IMap.aggregate(Aggregator, Predicate)` instead

  - ### Uses of JobTracker in com.hazelcast.instance

    Methods in com.hazelcast.instance that return JobTracker
    Modifier and Type | Method and Description
    --- | ---
    `JobTracker` | HazelcastInstanceProxy.`getJobTracker(String name)`
    `JobTracker` | HazelcastInstanceImpl.`getJobTracker(String name)`

  - ### Uses of JobTracker in com.hazelcast.mapreduce

    Methods in com.hazelcast.mapreduce that return JobTracker
    Modifier and Type | Method and Description
    --- | ---
    `JobTracker` | TrackableJob.`getJobTracker()` Deprecated. Returns the assigned `JobTracker`
