Hudson commented on HADOOP-11515: --------------------------------- FAILURE: Integrated in Hadoop-Yarn-trunk #1259 (See [https://builds.apache.org/job/Hadoop-Yarn-trunk/1259/]) HADOOP-11515. Upgrade jsch lib to jsch-0.1.51 to avoid problems running (ozawa: rev 33fefa33e51133aaf1e699e087e3bca2e8065eec) * hadoop-common-project/hadoop-common/CHANGES.txt * hadoop-project/pom.xml > 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 > Fix For: 2.8.0 > > 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! > Some references to problems reported: > - > http://sourceforge.net/p/jsch/mailman/jsch-users/thread/loom.20131009t211650-...@post.gmane.org/ > - https://issues.apache.org/bugzilla/show_bug.cgi?id=53437 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
