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

> 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}
