Capacity Planning using Dfsadmin command

[Abhishek Pratap Singh <ma...@gmail.com>]

Hi,



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?



Regards,

Abhishek

Hi Abhishek,
Although someone on this mailing list might know the answer to your question, I believe you'd be better off asking this question on the Hadoop mailing list.
