---------------------------------
Summary: resource manager fails to start if core-site.xml contains
an xi:include
Key: YARN-2210
URL: https://issues.apache.org/jira/browse/YARN-2210
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.4.0
Reporter: Sangjin Lee
Priority: Critical
The resource manager fails to start if core-site.xml contains an xi:include.
This is easily reproduced with a pseudo-distributed mode. Just add something
like this in the core-site.xml:
{noformat}
<configuration xmlns:xi="http://www.w3.org/2001/XInclude";>
<xi:include href="mounttable.xml"/>
...
{noformat}
and place mounttable.xml in the same directory (doesn't matter what the file is
really).
Then try starting the resource manager, and it will fail while handling this
include. The exception encountered:
{noformat}
[Warning] :20:38: Include operation failed, reverting to fallback. Resource
error reading file as XML (href='mounttable.xml'). Reason:
/Users/sjlee/hadoop-2.4.0/mounttable.xml (No such file or directory)
[Fatal Error] :20:38: An include failed, and no fallback element was found.

found.
