>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: auto-failover

>         Environment: If a site uses logjam protected ssh servers no common ciphers can be found and fencing breaks because the fencing process cannot be initiated by zkfc.

> Version 0.15.3 of jsch incorporates changes to add ciphers for logjam protection. See http://www.jcraft.com/jsch/ChangeLog.
> Since there are no developer visible changes, updating pom is sufficient.
> Doublechecked in my environment.
