Field Detail

MAX_NUMBER_OF_EVALUATORS

public static final OptionalParameter<Integer> MAX_NUMBER_OF_EVALUATORS

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.

DRIVER_CONFIGURATION_PROVIDERS

public static final OptionalImpl<ConfigurationProvider> DRIVER_CONFIGURATION_PROVIDERS

Configuration provides whose Configuration will be merged into all Driver Configuration.

RACK_NAMES

public static final OptionalParameter<String> RACK_NAMES

The rack names that will be available in the local runtime.

CONF

public static final ConfigurationModule CONF

The ConfigurationModule for the local resourcemanager.
