Example 1 with TaskExecutor

use of org.apache.flink.runtime.taskexecutor.TaskExecutor in project flink by apache.

the class MiniCluster method startTaskManager.

/**
 * Starts additional TaskManager process.
 *
 * <p>When the MiniCluster starts up, it always starts {@link
 * MiniClusterConfiguration#getNumTaskManagers} TaskManagers. All TaskManagers are indexed from
 * 0 to the number of TaskManagers, started so far, minus one. This method starts a TaskManager
 * with the next index which is the number of TaskManagers, started so far. The index always
 * increases with each new started TaskManager. The indices of terminated TaskManagers are not
 * reused after {@link #terminateTaskManager(int)}.
