      Description

      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.
