   @zjffdu Thanks for trying it out. Also, let me try again, but i had 
spark.app.name as commented out in the code that i posted just to show two 
different ways i was using to get it to work. 
   
   public Map<String, String> buildEnvFromProperties(InterpreterLaunchContext 
context) throws IOException {
       Map<String, String> env = super.buildEnvFromProperties(context);
       Properties sparkProperties = new Properties();
       String sparkMaster = getSparkMaster(properties);
       for (String key : properties.stringPropertyNames()) {
         if (RemoteInterpreterUtils.isEnvString(key)) {
           env.put(key, properties.getProperty(key));
         }
         if (isSparkConf(key, properties.getProperty(key))) {
           sparkProperties.setProperty(key, 
toShellFormat(properties.getProperty(key)));
         }
       }
   
       //env.put("SPARK_APP_NAME", context.getInterpreterGroupId() + 
"_testing");
       sparkProperties.setProperty("spark.app.name", 
context.getInterpreterGroupId() + "_testing");
   
       setupPropertiesForPySpark(sparkProperties);
       setupPropertiesForSparkR(sparkProperties);
       if (isYarnMode() && getDeployMode().equals("cluster")) {
         env.put("ZEPPELIN_SPARK_YARN_CLUSTER", "true");
         sparkProperties.setProperty("spark.yarn.submit.waitAppCompletion", 
"false");
       }
   
       StringBuilder sparkConfBuilder = new StringBuilder();
       if (sparkMaster != null) {
         sparkConfBuilder.append(" --master " + sparkMaster);
       }
       if (isYarnMode() && getDeployMode().equals("cluster")) {
         if (sparkProperties.containsKey("spark.files")) {
           sparkProperties.put("spark.files", 
sparkProperties.getProperty("spark.files") + "," +
               zConf.getConfDir() + "/log4j_yarn_cluster.properties");
         } else {
           sparkProperties.put("spark.files", zConf.getConfDir() + 
"/log4j_yarn_cluster.properties");
         }
         sparkProperties.put("spark.yarn.maxAppAttempts", "1");
       }```
