[jira] [Commented] (HADOOP-13644) Replace config key literal strings with config key names

["Chen Liang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-13644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15517512#comment-15517512 ] 

Chen Liang commented on HADOOP-13644:
-------------------------------------

I did some checking and it turns out there are actually a lot of usages like this in different modules. Based on some offline discussion with [~liuml07], we decided to fix them in a step-by-step fashion. Here the v001 patch only tries to resolve the use of {{"io.file.buffer.size"}} in hadoop-commons. Will file other JIRAs to solve other usages like such.

> 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.
