Subject [jira] [Commented] (ACCUMULO-3006) Don't allow viewfs in instance.volumes
Date Tue, 22 Jul 2014 16:44:38 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14070483#comment-14070483
] 

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.

> 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.
