Description
With zeppelin version 0.9.0-preview2, I'm able to read, write and execute new notebooks. But while trying to upgrade existing notes from version 0.8.1 to version 0.9.0-preview2, I get this exception when I run bin/upgrade-note.sh:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/security/UserGroupInformation at org.apache.zeppelin.notebook.FileSystemStorage.<clinit>(FileSystemStorage.java:43) at org.apache.zeppelin.notebook.repo.FileSystemNotebookRepo.init(FileSystemNotebookRepo.java:49) at org.apache.zeppelin.notebook.repo.NotebookRepoSync.init(NotebookRepoSync.java:84) at org.apache.zeppelin.notebook.repo.NotebookRepoSync.<init>(NotebookRepoSync.java:64) at org.apache.zeppelin.notebook.repo.UpgradeNoteFileTool.main(UpgradeNoteFileTool.java:41) Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.security.UserGroupInformation at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:419) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352) at java.lang.ClassLoader.loadClass(ClassLoader.java:352) ... 5 more
I'm storing notebooks on hdfs and my zeppelin-env.sh has the required env variable:
#!/bin/bash
export USE_HADOOP=true
