Since last couple of months I'm facing issues with hudson for hadoop project builds
http://hudson.zones.apache.org/hudson/view/ZooKeeper/job/Zookeeper-Patch-h1.grid.sp2.yahoo.net/61/console FATAL: command execution failed hudson.util.IOException2 <http://grepcode.com/search?query=hudson.util.IOException2> : Failed to join the process at hudson.Proc$RemoteProc.join(Proc.java:312) <http://grepcode.com/search/?query=hudson.Proc$RemoteProc.join&entity=method> at hudson.Launcher$ProcStarter.join(Launcher.java:275) <http://grepcode.com/search/?query=hudson.Launcher$ProcStarter.join&entity=method> at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:83) <http://grepcode.com/search/?query=hudson.tasks.CommandInterpreter.perform&entity=method> at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) <http://grepcode.com/search/?query=hudson.tasks.CommandInterpreter.perform&entity=method> at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) <http://grepcode.com/search/?query=hudson.tasks.BuildStepMonitor$1.perform&entity=method> at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:582) <http://grepcode.com/search/? ...... at hudson.Proc$RemoteProc.join(Proc.java:304) <http://grepcode.com/search/?query=hudson.Proc$RemoteProc.join&entity=method> ... 12 more I had to look into it closely and found a thread in the mailing list that say something like changing the slave configuration to use plink instead of hudson slaves in-built ssh. Here is the link to the thread on the mailing list http://n4.nabble.com/Builds-failed-last-night-with-IOException2-and-ChannelClosedException-traces-in-the-logs-td1593476.html Any thoughts?
