Disk usage in HDFS

[#1]

Hello everybody,

For ex. I have 1 TB of HDFS disk usage . I want to restrict the access to all the other disk drives

/data/

/apps/

/user/

/tmp/

/path1

/path2

In the above directories , I want my development team to use only 30 GB in /data where they can create/delete/modify the folders . If they want to use any other folder than /data . they should ask the operation team for permission to access the folders if not they should get permission denied error message.. I can exclude /tmp/,/user with 10Gb and 5GB respectiverly . What tools are good for this and how can we achieve this scenario.

Sorry for the basic question . @Geoffrey Shelton Okot Sir you could also help me in this regard. @Jay Kumar SenSharma

Take a look at HDFS quotas, that may be what you're after:
