Description

The `HDFS Quotas Guide` says

A quota of zero still permits files to be created, but no blocks can be added to the files.

But, this acutally is not so. When I tried, dfsadmin command failed with the below message.

$ hdfs dfsadmin -setSpaceQuota 0 /user/alice/dirWithSpaceQuota
setSpaceQuota: Invalid values for quota : 9223372036854775807 and 0
