List of killTask() Examples

Examples of killTask()

eu.stratosphere.nephele.executiongraph.ExecutionVertex.killTask()
Kills and removes the task represented by this vertex from the instance it is currently running on. If the corresponding task is not in the state RUNNING, this call will be ignored. If the call has been executed successfully, the task will change the state FAILED. @return the result of the task kill attempt
org.apache.hadoop.mapred.JobClient.NetworkedJob.killTask()
org.apache.hadoop.mapreduce.Job.killTask()
Kill indicated task attempt. @param taskId the id of the task to be terminated. @throws IOException
org.apache.hadoop.mapreduce.v2.api.MRClientProtocol.killTask()
org.apache.mesos.SchedulerDriver.killTask()
Kills the specified task. Note that attempting to kill a task is currently not reliable. If, for example, a scheduler fails over while it was attempting to kill a task it will need to retry in the future (these semantics may be changed in the future).
