I had resolved it.
The following is part of my core-site.xml:
<configuration xmlns:xi="http://www.w3.org/2001/XInclude";>
<xi:include href="./mountTable.xml" >
<xi:fallback></xi:fallback>
</xi:include>
<property>
<name>fs.defaultFS</name>
<value>viewfs://hadoop-cluster-xxx/</value>
<!-- <value>hdfs://h2m1:9000</value>-->

> 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.
> 14/06/24 23:30:16 FATAL conf.Configuration: error parsing conf

> found.
