Daryn Sharp commented on HADOOP-8146:
-------------------------------------
# I think it's overall a good idea, but dfsadmin is still subclassing
FsShell/Command. It's not using the rest of the logic, but I'd rather not
change nor risk destabilizing that command at this time. Would you be willing
to file a new jira?
# I wish I could, but the commands do not have public visibility to prevent
direct instantiation. All the loops for processing paths including a try loop
that catches IOException, so interrupts are always converted to exceptions.
The 2nd interrupt test does already exercise recursion into a directory.
Let me know if you want me to make further changes.

> Control-c is apparently generating {{InterruptedIOExceptions}}. The path
> processing loop traps {{IOException}}, displays the error, and moves to the
> next path. This means that recursive operations cannot be aborted.
