Oliver Heger commented on CONFIGURATION-609:
--------------------------------------------
This looks indeed like a bug. I will have a look (in the next few days). Thanks
for the report.
> When using a VFSFileSystem on a PropertiesConfiguration, processing an
> include token defaults back to DefaultFileSystem

> Key: CONFIGURATION-609
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-609
> Project: Commons Configuration
> Issue Type: Bug
> Components: File reloading
> Affects Versions: 2.0
> Environment: OSX using Eclipse/Maven
> Reporter: Patrick Ethier
>
> I have uploaded two files to HDFS.
> -----
> bob.properties:
> ==
> include=fred.properties
> ==
> ----
> fred.properties
> ==
> key=value
> ==
> ---
> If I load fred.properties and evaluated the "key", value is returned as
> expected. If I load bob.properties, I get a ConfigurationException.
> Here is the code snippet, please change setFileName() to reflect both cases:
> FileSystem fsTest = new VFSFileSystem();
> fsTest.setFileOptionsProvider(new HDFSOptionsProvider());
>
> Parameters params = new Parameters();
> FileBasedConfigurationBuilder<FileBasedConfiguration> builder =
> new
> FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfiguration.class)
> .configure(params.fileBased()
> .setLocationStrategy(new FileSystemLocationStrategy())
> .setBasePath("hdfs://localhost:8020/user/myusername")
> .setFileName("bob.properties")
> .setFileSystem(fsTest));
>
> Configuration config;
> try {
> config = builder.getConfiguration();
> System.out.println(config.getString("key"));
> } catch (ConfigurationException e) {
> e.printStackTrace();
> }
