@mxm , fortunately, this time I was able to run the tests on my machine. :)
I'm seeing a strange error. This is the error in Task manager log file for
per job detached streaming test:
```java
java.io.IOException: File or directory already exists. Existing files and
directories are not overwritten in NO_OVERWRITE mode. Use OVERWRITE mode to
overwrite existing files and directories.

This is surprising because I have made no changes to the way file writes or
overwrites are handled.
Here's the thing though: it should fail, because the folder is created at
line 475 in `YarnSessionFIFOITCase` and the program will need to overwrite it.
```java
File tmpOutFolder = null;
try{
tmpOutFolder = tmp.newFolder();
}
catch(IOException e) {
throw new RuntimeException(e);
}
```
But the tests always pass on the master branch.
The rest of the tests which follow this automatically fail because they
again check all the logs files for exception strings.
