Namenode log that indicates why it is not leaving safemode may be confusing
---------------------------------------------------------------------------

                 Key: HADOOP-5650
                 URL: https://issues.apache.org/jira/browse/HADOOP-5650
             Project: Hadoop Core
          Issue Type: Bug
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas
            Priority: Minor


A namenode with a large number of datablocks is setup with dfs.safemode.threshold.pct set
to 1.0. With a small number of unreported blocks, namenode prints the following as the reason
for not leaving safe mode:
{{The ratio of reported blocks 1.0000 has not reached the threshold 1.0000}}

With a large number of blocks, precision used for printing the log may not indicate the difference
between the actual ratio of safe blocks to total blocks and the configured threshold. Printing
number of blocks instead of ratio will improve the clarity.
