[jira] Commented: (HADOOP-3187) Quotas for name space management

    [ https://issues.apache.org/jira/browse/HADOOP-3187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593840#action_12593840 ] 

Doug Cutting commented on HADOOP-3187:
--------------------------------------

+1 This sounds like a good design to me.  I assume that one could set the quota on the root directory to something based on the amount of memory available on the namenode, as the simplest means of control, right?
