File Poller in 6.5 cluster not suppported

Hello All,
I would need a advice if there a fix to configure File Pooler in 6.5 Cluster nodes. I read some forums and I found its not supported. I would like to know why its not supported how we can implement it. I know we can write custom File Poller using WM Scheduler, I think we can do that but its not ideal. There should be some fix for this issue, any thoughts will be appreciated. Is there any alternatives approaches? If some one might have already implemented?

Thanks & Regards,
