Subject [jira] Updated: (HADOOP-2783) hod/hodlib/Common/xmlrpc.py uses HodInterruptException without importing it
Date Wed, 19 Mar 2008 10:26:24 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2783?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

> 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.
