compute2

public void compute2()

Description copied from class: H2O.H2OCountedCompleter

Override compute3() with actual work without having to worry about tryComplete()

Overrides:

compute2 in class H2O.H2OCountedCompleter<TaskGetKey>

onAck

public void onAck()

Description copied from class: DTask

2nd top-level execution hook. After the primary task has received a result (ACK) and before we have sent an ACKACK, this method is executed on the local vm. Transients from the local vm are available here.

Overrides:

onAck in class DTask<TaskGetKey>

onAckAck

public void onAckAck()

Description copied from class: DTask

3rd top-level execution hook. After the original vm sent an ACKACK, this method is executed on the remote. Transients from the remote vm are available here.
