Ravi Phulari commented on HDFS-846:
-----------------------------------
Also we need to correct ambiguous error message for setSpaceQuota value.
*setSpaceQuota: Invalid values for quota : 9223372036854775807 and 0*
This should be something like - *setSpaceQuota: Invalid value <user-input> for
setSpaceQuota : Allowed maximum spaceQuota = 9223372036854775807 and minimum
spaceQuota = 0*
{noformat}
[u...@ghost-host hadoop]$ hadoop dfsadmin -setSpaceQuota 0 /
setSpaceQuota: Invalid values for quota : 9223372036854775807 and 0
{noformat}
> SetSpaceQuota of value 9223372036854775807 does not apply quota.
