[jira] [Commented] (HDFS-11232) System.err should be System.out

["Ethan Li (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-11232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15740793#comment-15740793 ] 

Ethan Li commented on HDFS-11232:
---------------------------------

I noticed that System.out/err and LOG.info/err are both used for printing messages. I guess it's because LOG is used for system administrators, and System.out/err is used for users, right? 

What I submitted is very trivial. I'm not even sure if it's necessary to submit this kind of trivial thing. I am a newbie... hope to learn from you. Welcome to make comments.. Thanks very much!

> In /Users/Ethan/Worksplace/IntelliJWorkspace/hadoop/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/NameNode.java, System.err.println("Generating new cluster id:"); is used. I think it should be System.out.println(...) since this is not an error message
