Methods

Modifier and Type	Method and Description
void	disconnected(org.apache.mesos.ExecutorDriver executorDriver) Invoked when the executor becomes "disconnected" from the slave (e.g., the slave is being restarted due to an upgrade).
void	error(org.apache.mesos.ExecutorDriver executorDriver, String s) Invoked when a fatal error has occured with the executor and/or executor driver.
void	frameworkMessage(org.apache.mesos.ExecutorDriver executorDriver, byte[] bytes)
void	killTask(org.apache.mesos.ExecutorDriver executorDriver, org.apache.mesos.Protos.TaskID taskID) Invoked when a task running within this executor has been killed (via SchedulerDriver::killTask).
void	launchTask(org.apache.mesos.ExecutorDriver executorDriver, org.apache.mesos.Protos.TaskInfo taskInfo) Invoked when a task has been launched on this executor (initiated via Scheduler::launchTasks).
void	registered(org.apache.mesos.ExecutorDriver executorDriver, org.apache.mesos.Protos.ExecutorInfo executorInfo, org.apache.mesos.Protos.FrameworkInfo frameworkInfo, org.apache.mesos.Protos.SlaveInfo slaveInfo) Invoked once the executor driver has been able to successfully connect with Mesos.
void	reregistered(org.apache.mesos.ExecutorDriver executorDriver, org.apache.mesos.Protos.SlaveInfo slaveInfo) Invoked when the executor re-registers with a restarted slave.
void	shutdown(org.apache.mesos.ExecutorDriver executorDriver) Invoked when the executor should terminate all of it's currently running tasks.

Constructor Detail

SingularityExecutor

@Inject
public SingularityExecutor(SingularityExecutorMonitor monitor,
                          ExecutorUtils executorUtils,
                          SingularityExecutorTaskBuilder taskBuilder)

Method Detail

registered

public void registered(org.apache.mesos.ExecutorDriver executorDriver,
              org.apache.mesos.Protos.ExecutorInfo executorInfo,
              org.apache.mesos.Protos.FrameworkInfo frameworkInfo,
              org.apache.mesos.Protos.SlaveInfo slaveInfo)

Invoked once the executor driver has been able to successfully connect with Mesos. In particular, a scheduler can pass some data to it's executors through the FrameworkInfo.ExecutorInfo's data field.

Specified by:

registered in interface org.apache.mesos.Executor

reregistered

public void reregistered(org.apache.mesos.ExecutorDriver executorDriver,
                org.apache.mesos.Protos.SlaveInfo slaveInfo)

Invoked when the executor re-registers with a restarted slave.

Specified by:

reregistered in interface org.apache.mesos.Executor

disconnected

public void disconnected(org.apache.mesos.ExecutorDriver executorDriver)

Invoked when the executor becomes "disconnected" from the slave (e.g., the slave is being restarted due to an upgrade).

Specified by:

disconnected in interface org.apache.mesos.Executor

launchTask

public void launchTask(org.apache.mesos.ExecutorDriver executorDriver,
              org.apache.mesos.Protos.TaskInfo taskInfo)

Invoked when a task has been launched on this executor (initiated via Scheduler::launchTasks). Note that this task can be realized with a thread, a process, or some simple computation, however, no other callbacks will be invoked on this executor until this callback has returned.

Specified by:

launchTask in interface org.apache.mesos.Executor

killTask

public void killTask(org.apache.mesos.ExecutorDriver executorDriver,
            org.apache.mesos.Protos.TaskID taskID)

Invoked when a task running within this executor has been killed (via SchedulerDriver::killTask). Note that no status update will be sent on behalf of the executor, the executor is responsible for creating a new TaskStatus (i.e., with TASK_KILLED) and invoking ExecutorDriver::sendStatusUpdate.

Specified by:

killTask in interface org.apache.mesos.Executor

frameworkMessage

public void frameworkMessage(org.apache.mesos.ExecutorDriver executorDriver,
                    byte[] bytes)

Specified by:

frameworkMessage in interface org.apache.mesos.Executor

shutdown

public void shutdown(org.apache.mesos.ExecutorDriver executorDriver)

Invoked when the executor should terminate all of it's currently running tasks. Note that after a Mesos has determined that an executor has terminated any tasks that the executor did not send terminal status updates for (e.g., TASK_KILLED, TASK_FINISHED, TASK_FAILED, etc) a TASK_LOST status update will be created.

Specified by:

shutdown in interface org.apache.mesos.Executor

error

public void error(org.apache.mesos.ExecutorDriver executorDriver,
         String s)

Invoked when a fatal error has occured with the executor and/or executor driver. The driver will be aborted BEFORE invoking this callback.

Specified by:

error in interface org.apache.mesos.Executor
