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!
