class |
CancelJobSupervisorOperation
This operation is fired by the jobs owner node to remotely cancel the defined jobId on all nodes.
|
class |
FireNotificationOperation
This operation is used to transport and execute a notification on a remote node since
the current event service is not capable of reliable transmission so this is a fallback
to sync operations which is hopefully only a temporary workaround!
|
class |
GetResultOperation
This operation is used to retrieve results from a remote node
|
class |
KeysAssignmentOperation
This operation is used to request assignment for keys on the job owners node.
|
class |
NotifyRemoteExceptionOperation
This operation is used to inform the job owner of a remote exception
|
class |
PostPonePartitionProcessing
This operation is used to tell the job owner to postpone a mapping phase for the defined
partitionId.
|
class |
ProcessStatsUpdateOperation
This operation is used to update the process statistics on the owner node
|
class |
RequestMemberIdAssignment
This operation is used to do some kind of partitionId based processing on non partition based implementations
of
KeyValueSource (not implementing PartitionIdAware )
which can happen for custom data sources like distributed filesystems that are up to the end user on how to
manage the distribution. |
class |
RequestPartitionMapping
This operation requests a new partition to process by the requester on the job owning node
|
class |
RequestPartitionProcessed
This operation tells the job owner to mark a partition as fully processed
|
class |
RequestPartitionReducing
This operation tells the job owner to start reducing phase of the defined partition on the first
occurrence of a full emitted chunk
