Josh Elser commented on ACCUMULO-3006:
--------------------------------------
Do we have the ability to validate ViewFS that a mount point exists for the
trash directory (or one of its parent dirs)? At a minimum, we could even just
try to create/delete a file and see if we can do it when starting a service to
make sure the mount point exists, too.
> Don't allow viewfs in instance.volumes

> Key: ACCUMULO-3006
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3006
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.6.0
> Reporter: Dave Marion
> Priority: Blocker
> Fix For: 1.6.1, 1.7.0
>
>
> I think one of our folks put viewfs into instance.volumes on accident. File
> references in accumulo.root and accumulo.metadata were then written with
> viewfs in the path. The garbage collector then throws errors as compactions
> occur and it tries delete and move the files to the hdfs users trash
> directory.
> viewfs should never be allowed in instance.volumes property. It should fail.
