I have a strange issue. I'm not closing file system by .close() or .abort().
Locally my application is working perfectly, but when I try to do spark-submit on cluster I have got a lot of Exceptions

The last error is totally randomly, but it occurs 90% times when I'm using my app. Can be there be some with cluster configuration or my code is wrong?
Thanks
If the FileSystem is closed somewhere , the error will also occur when you use it again.

This is the error I see
Only reported by one user, and they are using a qnap server and they have a large number of files to process so I guess this is the key factor. But could the problem be caused by something I am doing wrong with by database handling (using hibernate and h2) or is this more likely I am doing something wrong with general file handling ?

From my analysis, here's what I can conclude :
In the stack trace, the root error, mainly java.util.MissingResourceException, doesn't seem like the real cause because the resource the process is trying to get exists and for the other process, this works fine.
I tried to see if the method used to get the resource, getBundle(), has some performance issue but I didn't find anything.
I also tried to see if this was an already existing IBM bug but if it is the case, I can't find it.
I am running the java code about svn which is like this

In my case, the destination folder contains staled .svn folder. After removing it everything works fine.
Anyone knows what is the reason for encountering this exception?
An exception is encountered during the processing. The stack track is below:

java.lang.ProcessImpl.start(ProcessImpl.java:65)
java.lang.ProcessBuilder.start(ProcessBuilder.java:451)

org.quartz.core.JobRunShell.run(JobRunShell.java:202)
org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:529)
If the exception is being thrown from the start() method, then the OS isn't able to fork/exec the process. So the problem isn't the subprocess dying, but that it's not being launched.
So are you specifying this correctly ? Are you relying on PATH settings ? Are the execute permissions correct ?
It would be useful to see the code that you use to initialise the ProcessBuilder. i.e. the invocation parameters.
