] | Creates a {@link RemoteEnvironment}. The remote environment sends (parts of) the program
to a cluster for execution. Note that all file paths used in the program must be accessible from the
cluster. The execution will use the cluster's default parallelism, unless the parallelism is
set explicitly via {@link ExecutionEnvironment#setParallelism(int)}.
@param host The host name or address of the master (JobManager), where the program should be executed.
@param port The port of the master (JobManager), where the program should be executed.
@param jarFiles The JAR files with code that needs to be shipped to the cluster. If the program uses
user-defined functions, user-defined input formats, or any libraries, those must be
provided in the JAR files.
