Subject [jira] [Commented] (ACCUMULO-1771) Instance id and version info only stored on one hdfs instance
Date Fri, 10 Jan 2014 20:31:51 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13868261#comment-13868261
] 

John Vines commented on ACCUMULO-1771:
--------------------------------------

bq. We can move data version to zookeeper, and put zookeeper instance name in accumulo-site.xml
to get the instanceId, rather than read from the hdfs path.

How do you plan doing the migration to that? And does this mean that you would have to init
and then distribute a new accumulo-site.xml to all of the nodes?

> When instance.volumes contains multiple uris only the first one is initialized with the
data version and instance id.   If the user changes the order of the uris in the config, it
seems like Accumulo will stop working correctly.
