[jira] [Commented] (DL-135) Cleanup System.out and System.err usage

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

    [ https://issues.apache.org/jira/browse/DL-135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15744071#comment-15744071 ] 

Liang Xie commented on DL-135:
------------------------------

cd incubator-distributedlog ,  grep -R "System.err" .      shows all of them are from *Tool , *Admin , *Benchmark, distributedlog-tutorials*,  so no further work need to be done.

and grep -R "System.out" seems shows only one line code needs to be modified (all others are from Tool class or tutorials)

> Based on the code analysis here : https://www.kiuwan.com/blog/analyzing_distributedlog_twitter-2/
> There are 272 calls to System.out and System.err usage. Most of them might just come from distributedlog tool. But let's still audit the code to make sure we are using System.out and System.err correctly.
