Christopher Tubbs commented on ACCUMULO-3006:
---------------------------------------------
Since the trash is supposed to be an HDFS feature, transparent to the
application, I'd not necessarily want to add special workarounds to Accumulo
code. I'd rather it be fixed in Hadoop or in user configuration, so we don't
over-scope Accumulo to start doing sanity checks on preconditions for features
which should be transparent.
> 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.
