Mona Chitnis commented on OOZIE-1778:
-------------------------------------
wouldn't StatusTransitService take care of this scenario since the bundle's
pending is set? There's ActionCheckerService running periodically for this
purpose too. We should enhance it for bundle-action recovery. currently it only
does wf-action and coord-action checks
> Rollback option for XCommand

> Project: Oozie
> Issue Type: Bug
> Reporter: Purshotam Shah
>
> Currently if we issue a command at bundle level, which set the pending for
> bundle action and issue child command.
> If child command succeed, then it's all good. But if child command at
> pre-check or acquiring lock fails, then there is no way to update parent.
> In this scenario, bundle action and remain in pending and will cause
> unexpected behavior.
> We should do something like
> {code:java}
> XCommand.call() throws CommandException {
> try {
> eagerVerifyPrecondition();
> acquireLockCron.start();
> acquireLock();
> acquireLockCron.stop();
> loadState();
> verifyPrecondition();
> ret = execute();
> }
> catch(Throwable e){
> handleFailure();
> }
> }
> {code}
