    hi @rmetzger ,
    I believe I find the reason why my test failed.
    A test will fail if we don’t specify “-t” argument(_which is an optional argument_)
in the command when call runWithArgs function, and we will get exception here:
    Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Level
        at org.apache.hadoop.mapred.JobConf.<clinit>(JobConf.java:357)
    It seems some jar files relevant to log callback are needed.
    One more thing, I noticed a segment of code as follows in the file “FlinkYarnSessionCli.java”:
    File logback = new File(confDirPath + File.pathSeparator + CONFIG_FILE_LOGBACK_NAME);
    if (logback.exists()) {
        flinkYarnClient.setFlinkLoggingConfigurationPath(new Path(logback.toURI()));
    And I wonder if “**File.pathSeparator**” should be “**File.separator**” here.
