[jira] [Created] (HADOOP-16007) Order of property settings is
incorrect when includes are processed
Jason Lowe created HADOOP-16007:
-----------------------------------
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.
