Subject [jira] [Commented] (ACCUMULO-1854) Accumulo{Input,Output}Format can't handle multiple configurations
Date Thu, 07 Nov 2013 05:26:17 GMT


ASF subversion and git services commented on ACCUMULO-1854:

Commit 5d3c3d5fdd2691f87a5319672c1d9f7dd29f457f in branch refs/heads/ACCUMULO-1854-multi-aif
from [~elserj]
[;h=5d3c3d5 ]

ACCUMULO-1854 Add AIF test to retrieve relevant configuration entries.
Remove the internal AtomicIntegers in favor of state management through
the Configuration object.

Using static concurrent structures in the InputFormat didn't work well
when making multiple calls to the class and altering the state. By
holding state on the Configuration for the input format, we can
alleviate some of this and do better duplication checking.

>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.4.4, 1.5.0
>            Reporter: Josh Elser
>            Assignee: Josh Elser
>             Fix For: 1.4.5, 1.5.1, 1.6.1
> I noticed that I was unable to properly use MultipleInputs (or any code which uses a
similar approach) with the AccumuloInputFormat class because of the way it builds up information
in the Configuration object.
> It would be useful to be able to have multiple instances of AIF (and AOF) configured
within one Job (Configuration).
