Description

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.

[ebadger@foobar bin]$ hadoop fs -cat /foo 2>/dev/null
