> Enable fencing for logjam-protected ssh servers
> -----------------------------------------------
>
> Key: HADOOP-12781
> URL: https://issues.apache.org/jira/browse/HADOOP-12781
> Project: Hadoop Common
> Issue Type: Bug
> Components: auto-failover
> Affects Versions: 2.7.2
> 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.
> Reporter: Olaf Flebbe
> Assignee: Olaf Flebbe
> Attachments: HADOOP-12781.1.patch
>
>
> 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.
