Namenode does not leave safe mode even if all blocks are available
------------------------------------------------------------------
Key: HDFS-645
URL: https://issues.apache.org/jira/browse/HDFS-645
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.20.1
Reporter: Qi Liu
When the safe mode threshold is set to 1.0f, sometimes the name node does not
leave safe mode even if all blocks are available. This is caused by floating
point number division and comparison issues.
