how to increase DFS capacity
I want to increase DFS capacity. Which command I should use?
Using "hadoop dfsadmin -report", the following is my current configuration.
Configured Capacity: 53687091200 (50 GB)
Present Capacity: 2568660701 (2.39 GB)
DFS Remaining: 2560737280 (2.38 GB)
DFS Used: 7923421 (7.56 MB)
DFS Used%: 0.31%
How can I increase Present Capacity?

Moving this to the hdfs-user@ list. Please use that list in the future
for HDFS specific queries.

Has a quota been set upon your user by your cluster's administrator?
What's the output of df -h on your dfs.data.dir directory's disk?

Present capacity is generally the space freely available on the disk.
Perhaps your disk is full, if no quote has been applied?

My problem i: when running my program, it always issues " Disc quota
exceeded" error.
I checked with "hadoop dfsadmin -report" command, it shows DFS Used: 98%
So, how do I increase Present capacity to solve this problem?
