Vinod Kumar Vavilapalli updated HADOOP-2783:
--------------------------------------------
Attachment: HADOOP-2783.2
The concerned code path raising HodInterruptedException is traversed when any
rpc method returns an exception and by that time hod interrupt is set. To test
this method, we need to mimic a user given keyboard interrupt, which doesn't
seem possible/straight-forward because of threading issues. So falling back to
indirect way of testing the patch - 1) setting interrupt even before calling
rpc method and 2) let calling rpc method return an exception by giving invalid
rpc host address. (2) could also have been done by having a rpc method that
simply raises an exception.
> hod/hodlib/Common/xmlrpc.py uses HodInterruptException without importing it

> And because of this no-import of HodInterruptException in
> hod/hodlib/Common/xmlrpc.py, HOD fails with an exception, when it gets
> interrupted by user(e.g ^C) while it is performing any xmlrpc request. One
> line fix.
