Subject [jira] Commented: (HDFS-846) SetSpaceQuota of value 9223372036854775807 does not apply quota.
Date Mon, 21 Dec 2009 20:41:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793349#action_12793349
] 

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}
[user@ghost-host hadoop]$ hadoop dfsadmin -setSpaceQuota 0 /
setSpaceQuota: Invalid values for quota : 9223372036854775807 and 0
{noformat}
