Subject [jira] Created: (HDFS-645) Namenode does not leave safe mode even if all blocks are available
Date Wed, 23 Sep 2009 00:47:16 GMT
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.
