Eric Badger commented on HDFS-14759:
------------------------------------
I have put up a patch to change the log line back to debug. However, this may
not be the correct fix. I don't know why logging is going to stdout at all,
regardless of the level. The correct fix might be to modify FSShell to write
all logging to stderr. There may have been a regression there.

> HDFS-13699 changed a debug log line into an info log line and this line is
> printed during {{hadoop fs -cat}} operations. This make it very difficult to
> figure out where the log line ends and where the catted file begins,
> especially when the output is sent to a tool for parsing.
