Subject [jira] [Updated] (YARN-1078) TestNodeManagerResync, TestNodeManagerShutdown, and TestNodeStatusUpdater fail on Windows
Date Tue, 10 Sep 2013 22:10:51 GMT

     [ https://issues.apache.org/jira/browse/YARN-1078?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chuan Liu updated YARN-1078:
----------------------------

    Attachment: YARN-1078.2.patch

I looked into the failure. It turns out we use InetAddress.getCanonicalHostName() to construct
nodeId in "ContainerManagerImpl". In the test, we assume this will always be "localhost" for
a local loop back address, i.e. 127.0.0.1. However, this is not the case on Windows. As the
method could return "127.0.0.1" on Windows instead of "localhost". In the old patch, I switch
from "localhost" to "127.0.0.1", and regressed Linux. Attach a new patch that uses getCanonicalHostName()
to obtain the name for nodeId constructed in the tests.

i.e. 127.0.0.1 does not resolve to host name "localhost".
