Subject [jira] [Commented] (ACCUMULO-3006) Don't allow viewfs in instance.volumes
Date Tue, 22 Jul 2014 16:38:39 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14070475#comment-14070475
] 

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.

> 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.
