Restricting quota for users in HDFS

Hi all,

 

We have chown command in hadoop dfs to make a particular directory own
by a person. Do we have something similar to create user with some space
limit/restrict the disk usage by a particular user?

 

Thanks

Pallavi

Yeah. I meant the same. I want to restrict a directory which is owned by
a particular user.

Thanks
Pallavi

    Quotas are implemented on a per-directory basis, not per-user.
There
is no support for "this user can have X space, regardless of where
he/she
writes" only "this directory has a limit of X space, regardless of who
writes there."

Take a look at HDFS Quotas Guide .
