> Possible dead-lock in SignalXCommand

> Key: OOZIE-3646

> Project: Oozie
> Issue Type: Bug
> Reporter: Junfan Zhang
> Assignee: Junfan Zhang
> Priority: Major
> Attachments: OOZIE-3646-002.patch, OOZIE-3646-003.patch,

> The limited thread execution mechanism aims to solve the dead-lock when all
> active threads are executing the SignalXCommand's invokeAll method.
> h2. Dead-lock when to happen
> Assuming that Oozie CallableQueue thread pool size is 120, when all threads
> are executing the {{SignalXCommand.startForkedActions}} method, a deadlock
> occurs.
> Because in {{SignalXCommand.startForkedActions}}, the code of
> {code:java}
> List<Future<ActionExecutorContext>> futures =
> Services.get().get(CallableQueueService.class)
> .invokeAll(tasks);
> {code}
> will be sync executed, however now all callableQueue threads are busy.
> h2. Solution
> 1. Need to limit directly invokeAll call when the num of rest threads is less
> than the tasks
> 2. To obtain correct active threads number in callableQueue, the
> SignalXCommand.class lock is needed.
