Hello,
I am able to submit Job on Spark cluster from Windows desktop. But the
executors are not able to run.
When I check the Spark UI (which is on Windows, as Driver is there) it shows
me JAVA_HOME, CLASS_PATH and other environment variables related to Windows.
I tried by setting spark.executor.extraClassPath to Unix classpath,
spark.getConf().setExecutorEnv("spark.executorEnv.JAVA_HOME",
"/usr/lib/jvm/java-6-openjdk-amd64") within program but it didn't helped.
The executor gives below mentioned error. Can you please let me know what I
am missing ?
