Sean Owen commented on SPARK-1693: ---------------------------------- As I recall this happens because the official JavaEE servlet API jar includes MANIFEST.MF entries with a signature. If these classes are repackaged in an assembly jar with these same MANIFEST.MF entries, you get this failure. There's a lot of discussion above, but one quick fix is to manage to not include the signatures from anywhere. > Dependent on multiple versions of servlet-api jars lead to throw an > SecurityException when Spark built for hadoop 2.3.0 , 2.4.0 > -------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-1693 > URL: https://issues.apache.org/jira/browse/SPARK-1693 > Project: Spark > Issue Type: Bug > Components: Spark Core > Reporter: Guoqiang Li > Assignee: Guoqiang Li > Priority: Blocker > Fix For: 1.0.0 > > Attachments: log.txt > > > {code}mvn test -Pyarn -Dhadoop.version=2.4.0 -Dyarn.version=2.4.0 > > log.txt{code} > The log: > {code} > UnpersistSuite: > - unpersist RDD *** FAILED *** > java.lang.SecurityException: class "javax.servlet.FilterRegistration"'s > signer information does not match signer information of other classes in the > same package > at java.lang.ClassLoader.checkCerts(ClassLoader.java:952) > at java.lang.ClassLoader.preDefineClass(ClassLoader.java:666) > at java.lang.ClassLoader.defineClass(ClassLoader.java:794) > at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) > at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) > at java.net.URLClassLoader.access$100(URLClassLoader.java:71) > at java.net.URLClassLoader$1.run(URLClassLoader.java:361) > at java.net.URLClassLoader$1.run(URLClassLoader.java:355) > at java.security.AccessController.doPrivileged(Native Method) > at java.net.URLClassLoader.findClass(URLClassLoader.java:354) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
