Field Detail

NUMBER_OF_THREADS

public static final OptionalParameter<Integer> NUMBER_OF_THREADS

The number of threads or processes available to the resourcemanager. This is the upper limit on the number of Evaluators that the local resourcemanager will hand out concurrently. This simulates the size of a physical cluster in terms of the number of slots available on it with one important caveat: The Driver is not counted against this number.

RUNTIME_ROOT_FOLDER

public static final OptionalParameter<String> RUNTIME_ROOT_FOLDER

The folder in which the sub-folders, one per Node, will be created. Those will contain one folder per Evaluator instantiated on the virtual node. Those inner folders will be named by the time when the Evaluator was launched.

If none is given, a folder "REEF_LOCAL_RUNTIME" will be created in the local directory.

JVM_HEAP_SLACK

public static final OptionalParameter<Double> JVM_HEAP_SLACK

The fraction of the container memory NOT to use for the Java Heap.

CONF

public static final ConfigurationModule CONF

The ConfigurationModule for the local resourcemanager.
