Mingliang Liu updated HDFS-8053:
--------------------------------
Attachment: HDFS-8053.003.patch
Thank you [~wheat9]. The v3 patch adds a new {{HdfsConfigurationLoader}} class
which loads default resources files. The class is like following:
{code:title= HdfsConfigurationLoader.java}
public class HdfsConfigurationLoader {
/** Load the default resources.
*
* This method is idempotent as the {@link Configuration#addDefaultResource}
* will only add the default resources once, in the order of their appearance.
*/
public static void load() {
// adds the default resources
Configuration.addDefaultResource("hdfs-default.xml");
Configuration.addDefaultResource("hdfs-site.xml");
}
}
{code}
The {{DFSClient$Renewer}} will call this method instead of
{{HdfsConfiguration#init}} at its static initialization section.
> Move DFSIn/OutputStream and related classes to hadoop-hdfs-client

> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: build
> Reporter: Haohui Mai
> Assignee: Mingliang Liu
> Attachments: HDFS-8053.000.patch, HDFS-8053.001.patch,
> HDFS-8053.002.patch, HDFS-8053.003.patch
>
>
> This jira tracks the effort of moving the {{DFSInputStream}} and
> {{DFSOutputSream}} classes from {{hadoop-hdfs}} to {{hadoop-hdfs-client}}
> module.
> Guidelines:
> * As the {{DFSClient}} is heavily coupled to these two classes, we should
> move it together.
> * Related classes should be addressed in separate jiras if they're
> independent and complex enough.
> * The checkstyle warnings can be addressed in [HDFS-8979 |
> https://issues.apache.org/jira/browse/HDFS-8979]
> * Removing the _slf4j_ logger guards when calling {{LOG.debug()}} and
> {{LOG.trace()}} can be addressed in [HDFS-8971 |
> https://issues.apache.org/jira/browse/HDFS-8971].
