Description:
Safe mode tip is printed every 20 seconds.

Old
{code:java}
STATE* Safe mode ON. The reported blocks 111054015 needs additional 27902753
blocks to reach the threshold 0.9990 of total blocks 139095856. The number of
live datanodes 2531 has reached the minimum number 1. Safe mode will be turned
off automatically once the thresholds have been reached.{code}
New
{code:java}
STATE* Safe mode ON.
The reported blocks 134851250 needs additional 3218494 blocks to reach the
