>                 Key: HDFS-7376
>                 URL: https://issues.apache.org/jira/browse/HDFS-7376
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: build
>            Reporter: Johannes Zillmann

> We had an application sitting on top of Hadoop and got problems using jsch once we switched
to java 7. Got this exception:
> {noformat}
>  com.jcraft.jsch.JSchException: verify: false
> 	at com.jcraft.jsch.Session.connect(Session.java:330)
> 	at com.jcraft.jsch.Session.connect(Session.java:183)
> {noformat}
> Upgrading to jsch-0.1.51 from jsch-0.1.49 fixed the issue for us, but then it got in
conflict with hadoop's jsch version (we fixed this for us by jarjar'ing our jsch version).
> So i think jsch got introduce by namenode HA (HDFS-1623). So you guys should check if
the ssh part is properly working for java7 or preventively upgrade the jsch lib to jsch-0.1.51!
