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!
> System.err should be System.out
