java.io.IOException: Filesystem closed After running java action

[Serega Sheypak <se...@gmail.com>]

Hi, I'm getting weird exception while running Java action.

This log line is the LAST line of code in main method. There are no
System.exit or something like that. Main method is executed without any
exceptions.
***
2014-05-12 00:15:02,238 INFO my.java.MainClass: AFTER!!! ToolRunner.run(new
Tools(), args);
***
Then exception happens. I have no idea what is going on. There are no
ERROR/WARN in oozie server log or oozie workflow log. How can I debug it?

2014-05-12 00:15:02,238 INFO my.java.MainClass: AFTER!!! ToolRunner.run(new
Tools(), args);
