Hi, Not clear how this computation is done
For sake of discussion Say the machine with data node has two disks /disk1 and /disk2. And each of these disk has a directory for data node and a directory for non-datanode usage. /disk1/datanode /disk1/non-datanode /disk2/datanode /disk2/non-datanode The dfs.datanode.data.dir says "/disk1/datanode,/disk2/datanode". With this, what does the DFS and NonDFS indicates? Does it indicates SUM(/disk*/datanode) & SUM(/disk*/non-datanode) etc. resp. ? Thanks,
