Subject [jira] [Commented] (MAPREDUCE-3147) Handle leaf queues with the same name properly
Date Wed, 16 Nov 2011 02:56:52 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150985#comment-13150985
] 

Nathan Roberts commented on MAPREDUCE-3147:
-------------------------------------------

What I would like to avoid is one subtree limiting the namespace of another. One of the selling
points behind the hierarchical queue structure is that an owner of a subtree can manage that
subtree independently of the others. If the leaves of the tree are required to have globally
unique names, it doesn't seem like we're quite meeting that goal (my subtree can't add a queue
called "default", if someone else has already taken that name). Is there no way we can maintain
compatibility AND get to independent namespaces? Could we support the concept of an alias
whereby relative queue names can be linked into the hierarchy "d->root.a.b.c.d"?

> If there are two leaf queues with the same name, there is ambiguity while submitting
jobs, displaying queue info. When such ambiguity exists, the system should ask for clarification
/ show disambiguated information.
