> This happens when we terminate the JT using _control-C_. It throws the
> following exception
> {noformat}
> Exception closing file my-file
> java.io.IOException: Filesystem closed

> Note that _my-file_ is some file used by the JT.
> Also if there is some file renaming done, then the exception states that the
> earlier file does not exist. I am not sure if this is a MR issue or a DFS
> issue. Opening this issue for investigation.
