>          Issue Type: New Feature
>            Reporter: Andor Molnar
>            Assignee: Andor Molnar
>            Priority: Major
>             Fix For: 3.5.4, 3.6.0
> In the even that the zookeeper transaction log or snapshot become corrupted 
> and fail CRC checks (preventing startup) we should have a mechanism to get 
> the cluster running again.
> Previously with achieved this by loading the broken transaction log with a 
> modified version of ZK with disabled CRC check and forced it to snapshot.
> It'd very handy to have a tool which can do this for us. LogFormatter and 
> SnapshotFormatter have already been designed to dump log and snapshot files, 
> it'd be nice to extend their functionality and add ability for such recovery.
