Ravi Prakash commented on HDFS-4888:
------------------------------------
The change in behavior is:
1. Prints a "It was turned on manually" when the safemode was initially entered
into manually.
2. Prints the "The number of live datanodes %d has reached...." message when in
extension mode. Previously only the "The reported blocks %d has reached the
threshold" message was printed.
> Refactor and fix FSNamesystem.getTurnOffTip to sanity
