> The documentation at
> http://hadoop.apache.org/common/docs/r0.20.0/hdfs_quota_admin_guide.html says
> that the max quota size is Long.Max_Value which is = 9223372036854775807, but
> as you can see above, setting the quota to this value returns no error but
> doesn't actually change the quota value. Long.Max_Value - 1 works though.. so
> the documentation should be changed to reflect this behavior. Long.Max_Value
> + 1 returns an actual error (though it isn't the same as the negative number
> error):
> [root@c1204 hadoop]# sudo -u hdfs hdfs dfsadmin -setSpaceQuota
> 9223372036854775808 testQuotaFolder
> setSpaceQuota: For input string: "9223372036854775808"
> Usage: java DFSAdmin [-setSpaceQuota <quota> <dirname>...<dirname>]
> [root@c1204 hadoop]# sudo -u hdfs hdfs dfsadmin -setSpaceQuota -1
