Subject Capacity Planning using Dfsadmin command
Date Tue, 22 Nov 2011 15:34:29 GMT

I have a query about hadoop, this is very important for capacity planning
and requesting new hardware.

      Hadoop command: *hadoop dfsadmin –report* depicts the DFS usage and
DFS remaning. I have checked that the DFS usage does not match the
size of *hadoop
dfs –dus* on root or user directory. The difference is high enough, means
dfsadmin shows occupied space as 5TB but dus shows it is 3.5TB.

Does anyone knows why there is a more space occupied shown in dfsadmin?
