-----------------------------------------
RAT failure is known and covered in HDFS JIRAs; don't worry about it
> Upgrade jsch lib to jsch-0.1.51 to avoid problems running on java7

> Key: HADOOP-11515
> URL: https://issues.apache.org/jira/browse/HADOOP-11515
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 2.6.0
> Reporter: Johannes Zillmann
> Assignee: Steve Loughran
> Labels: BB2015-05-TBR
> Attachments: HADOOP-11515.001.patch, HDFS-7376.1.patch

> 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!
