Example 1 with FailedActionException

use of es.bsc.compss.scheduler.exceptions.FailedActionException in project compss by bsc-wdc.

the class TaskScheduler method errorOnAction.

 * any possible solution to re-execute it. This code is executed only on re-schedule (no resubmit)
 *
 * @param action
 *            action raising the error
