Subject [jira] [Commented] (ACCUMULO-1832) Create utility for rewriting uris
Date Sun, 03 Nov 2013 04:01:18 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812251#comment-13812251

Christopher Tubbs commented on ACCUMULO-1832:
---------------------------------------------

How would you be in the same boat? This is a unique problem because of the fact that 1.6 stores
full URIs, whereas 1.5 and earlier only stored relative paths. You could replace the namenode
with a backup on a different server and things would just work (in theory, anyway).

> 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.
