Hi, I am usring flink single-job mode on YARN. After i upgrade flink verson from 1.3.2 to 1.4.0, the parameter "yarn.taskmanager.env.JAVA_HOME" doesn’t work as before. I can only found error log on yarn like this:
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/flink/yarn/YarnApplicationMasterRunner : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) 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$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482) Is there something different i should know to avoid this problem ? Thanks!
