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

Per offline discussion, we address this issue by modules. This JIRA is to track the effort of HDFS module, and [HADOOP-13658] is about the hadoop common module. We can create separate JIRAs for other modules like hadoop tools, yarn, mapreduce, etc, for easy review and Jenkins pre-commit.

> There are some places that use config key literal strings instead of config key names, e.g.
> {code:title=IOUtils.java}
>     copyBytes(in, out, conf.getInt("io.file.buffer.size", 4096), true);
> {code}
> We should replace places like this.
