Dear Alex
"""Has anyone else experienced this behavior?"""" Yes, I had also experienced and raised jira for same.. Please have look on following issue.. https://issues.apache.org/jira/browse/HDFS-5215 ________________________________________ From: alex bohr [alexjb...@gmail.com] Sent: Wednesday, October 30, 2013 1:07 AM To: user@hadoop.apache.org Subject: Namenode doesn't accurately know datanodes free-space I see that the Namenode always reports datanodes as having about 5% more space then they actually do. And I recently added some smaller datanodes into the cluster and the drives filled up to 100%, not respecting the 5GB I had reserved for Map Reduce with this property from mapred-site.xml: <property> <name>dfs.datanode.du.reserved</name> <value>5368709120</value> </property> Has anyone else experienced this behavior?
