---------------------------------------
Summary: Upgrade jsch lib to jsch-0.1.51 to avoid problems running
on java7
Key: HDFS-7376
URL: https://issues.apache.org/jira/browse/HDFS-7376
Project: Hadoop HDFS
Issue Type: Bug
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!
