I have configured a three node cluster:
For each data node the configured capacity is showing double the size of actual storage. Below is the screen shot of configuration files, “dfsadmin –report” and “df –h” from each node. Any idea why would it show configured capacity as double the size of actual storage?
After looking at configuration files, I am assuming each directory mentioned under “dfs.data.dir” is being treated as a separate storage device and hence doubling the configured capacity size. Am I correct? Is this a bug or something wrong with my configuration?
CORE-SITE.XML, HDFS-SITE.XML, MAPRED-SITE.XML (From all nodes)
R1NN1 (NAMENODE, DATANODE, JOBTRACKER)
R1SN1 (SECONDARY NAMENODE, DATANODE, TASKTRACKER)
