Default checkpoint supported checker.
Most tasks will support checkpointing by default unless they do output
during the computation. Some tasks however can use non-checkpointable
features, e.g.: static variables to pass data around between supersteps
or new threads started from MasterCompute or external resources. In that
case to prevent accidental checkpointing you should provide checker
Does the job support checkpoints?
It is true by default, set it to false if your job uses some
- static variables for storing data between supersteps.
- starts new threads or uses Timers
- writes output before job is complete, etc
This method is called on master and has access to
job configuration and master compute.
