Josh Elser commented on ACCUMULO-1854:
--------------------------------------
First off, thanks to [~ctubbsii] and [~bills] because they were both helpful in
talking this out.
Came to the conclusion that I don't need to rework the Configuration object,
but instead could leverage all of the necessary information inside of the
RangeInputSplit class (instead of just the location and Range as it currently
contains). This allows us to let multiple invocations of the
AccumuloInputFormat create RangeInputSplits without requiring all of the
connection information contained in the Configuration.
This creates a *much* cleaner changeset as well as backwards compatibility with
the current implementation which falls back to using the information in the
Configuration when the information is not present (null) in the RangeInputSplit.
> Accumulo{Input,Output}Format can't handle multiple configurations

> Key: ACCUMULO-1854
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1854
> 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).
