Dave Marion commented on ACCUMULO-1832:
---------------------------------------
I like the idea of using a prefix (see [1]) instead of full URL. If there were
a mapping of prefix to namenode address in the configuration, would that make
rename operations simpler? It's like viewfs to some degree, but I think it
allows greater flexibility in the long run as viewfs is limited to directories.
In another release when we have a pluggable file placement strategy, then we
could add weights or priority to the different prefixes.

> Key: ACCUMULO-1832
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1832
> Project: Accumulo
> Issue Type: Sub-task
> Components: master, tserver
> Reporter: Keith Turner
> Assignee: Eric Newton
> Priority: Blocker
> Fix For: 1.6.0
>
>
> When a users namenode dies and they restore it on another node Accumulo will
> not work since it stores fully qualified uris internally. Need to a provide
> a utility to rewrite these URIs.
> The utility could rewrite paths in zookeeper, bring root table online and
> rewrite paths, bring metadata table online and rewrite, and then allow user
> tablets to come online.
