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.
