Subject [jira] [Commented] (YARN-2210) resource manager fails to start if core-site.xml contains an xi:include
Date Sat, 03 Dec 2016 06:47:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-2210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15717566#comment-15717566

followtry commented on YARN-2210:
---------------------------------

I had resolved it.
The following is part of  my core-site.xml:

```
 <xi:include href="./mountTable.xml" >
                  <xi:fallback></xi:fallback>
</xi:include>
```

>             Project: Hadoop YARN

>          Components: resourcemanager

> 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)
