Subject [jira] [Created] (ACCUMULO-3215) Bulk import tries to use default DFS directory instead of configured
Date Thu, 09 Oct 2014 00:21:33 GMT
Josh Elser created ACCUMULO-3215:
------------------------------------

             Summary: Bulk import tries to use default DFS directory instead of configured
                 Key: ACCUMULO-3215
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3215
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.6.1
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Critical
             Fix For: 1.6.2, 1.7.0


Ran Shard randomwalk and saw a failure about a bulk imported file. Oddly, the path that it
referenced was for the default dfs directory /accumulo instead of the configured volume I
set /apps/accumulo.

Additionally, bulk import is placing relative paths into metadata and not absolute paths,
which also seems rather strange.
