-----------------------------------

             Summary: Order of property settings is incorrect when includes are processed
                 Key: HADOOP-16007
                 URL: https://issues.apache.org/jira/browse/HADOOP-16007
             Project: Hadoop Common
          Issue Type: Bug
          Components: conf
    Affects Versions: 3.1.1, 3.2.0, 3.0.4
            Reporter: Jason Lowe


If a configuration file contains a setting for a property then later includes another file that also sets that property to a different value then the property will be parsed incorrectly. For example, consider the following configuration file:
{noformat}
<configuration xmlns:xi="http://www.w3.org/2001/XInclude">
     <property>
         <name>myprop</name>
         <value>val1</value>
     </property>
<xi:include href="/some/other/file.xml"/>
</configuration>
{noformat}
with the contents of /some/other/file.xml as:
{noformat}
     <property>
       <name>myprop</name>
       <value>val2</value>
     </property>
{noformat}
Parsing this configuration should result in myprop=val2, but it actually results in myprop=val1.
