hi @rmetzger ,
I believe I find the reason why my test failed.
A test will fail if we donât specify â-tâ 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
âFlinkYarnSessionCli.javaâ:
```
File logback = new File(confDirPath + File.pathSeparator +
CONFIG_FILE_LOGBACK_NAME);
if (logback.exists()) {
shipFiles.add(logback);
flinkYarnClient.setFlinkLoggingConfigurationPath(new
Path(logback.toURI()));
}
```
And I wonder if â**File.pathSeparator**â should be
â**File.separator**â here.
