I started building ESXI to be compatible with camp nav vcware to work with my 
hyperv. all was well until I went to make the disk. Windows 10 doesn't work so 
I'm downloading Windows 7

> partitions being reassigned

>             Project: Kafka
>          Issue Type: Improvement
>          Components: controller, core
>    Affects Versions: 1.0.0
>            Reporter: Jiangjie Qin

> Currently the controller will not process the partition reassignment of a 
> partition if the partition is already being reassigned.
> The issue is that if there is a broker failure during the partition 
> reassignment, the partition reassignment may never finish. And the users may 
> want to cancel the partition reassignment. However, the controller will 
> refuse to do that unless user manually deletes the partition reassignment zk 
> path, force a controller switch and then issue the revert command. This is 
> pretty involved. It seems reasonable for the controller to replace the 
> ongoing stuck reassignment and replace it with the updated partition 
> assignment.
