Josh Elser commented on ACCUMULO-2719:
--------------------------------------
[~dlmarion], can you elaborate on your configuration here (notably the
instance.* values in accumulo-site.xml and your viewfs mount table)? You're
trying to run Accumulo over ViewFS, but as I understand it, viewfs presents a
single Hadoop FileSystem over multiple DFS instances using mount-points, so I'm
confused as to the environment.
You mention {{instance.volumes}}, but I would have thought that you'd use
viewfs to try to alleviate the need to specify multiple volumes when you only
want to pin a certain table to a given filesystem (and not spread files across
many filesystems).
Also, how/where did {{accumulo init}} write the instance_id?

> Key: ACCUMULO-2719
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2719
> Project: Accumulo
> Issue Type: Bug
> Components: shell
> Affects Versions: 1.6.0
> Reporter: Dave Marion
> Priority: Minor
>
> Shell fails to find instance id at /accumulo/instance_id when just the name
> service roots are configured in viewfs. Fails at
> ZooUtil.getInstanceIDFromHDFS(line 63). I'm thinking the code should prepend
> one of the instance.volumes.
> Workaround is to explicitly map /accumulo/instance_id in viewfs to one of the
> locations.
