Sean Owen resolved SPARK-12223. ------------------------------- Resolution: Won't Fix I don't think Yosemite has Java 6? or mine doesn't at least. I don't know that you can reliably detect and report this error, since the failure comes pretty early. Spark was on Java 7 in 1.4, I think? so this is pretty old news. I agree, I do not see much value in adding more code to try to report this. Spark may be onto Java 8 in 2.x, even. > Warn users if Spark 1.5 is run on JRE6 > -------------------------------------- > > Key: SPARK-12223 > URL: https://issues.apache.org/jira/browse/SPARK-12223 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.5.0, 1.5.1, 1.5.2 > Environment: $ uname -a > Darwin grixis 14.5.0 Darwin Kernel Version 14.5.0: Tue Sep 1 21:23:09 PDT > 2015; root:xnu-2782.50.1~1/RELEASE_X86_64 x86_64 > $ java -version > java version "1.6.0_65" > Java(TM) SE Runtime Environment (build 1.6.0_65-b14-466.1-11M4716) > Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-466.1, mixed mode) > Reporter: Dan Adkins > > I downloaded the latest release (1.5.2) from > [http://spark.apache.org/downloads.html] and attempted to execute step 1 of > the Python quick start guide > [http://spark.apache.org/docs/latest/quick-start.html]. > $ ./bin/pyspark > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/spark/launcher/Main > Caused by: java.lang.ClassNotFoundException: org.apache.spark.launcher.Main > at java.net.URLClassLoader$1.run(URLClassLoader.java:202) > at java.security.AccessController.doPrivileged(Native Method) > at java.net.URLClassLoader.findClass(URLClassLoader.java:190) > at java.lang.ClassLoader.loadClass(ClassLoader.java:306) > at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) > at java.lang.ClassLoader.loadClass(ClassLoader.java:247) > This looks similar to SPARK-1703 which is caused by attempting to run a Java7 > jar with JRE 6.
