------------------------------------
[~elserj] Do you have update on this? I'm trying to upgrade accumulo dependency
in hive, but seems I'm hitting this issue for the tests.
> NPE extracting samplerConfiguration from InputSplit

> AbstractInputFormat extracts a default table configuration object from the
> Job's Configuration class:
> {code}
> InputTableConfig tableConfig = getInputTableConfig(job,
> baseSplit.getTableName());
> {code}
> Eventually, the same class tries to extract the samplerConfiguration from
> this tableConfig (after noticing it is not present in the InputSplit) and
> this throws an NPE. Somehow the tableConfig was null. It very well could be
> that Hive was to blame, I just wanted to make sure that this was captured
> before I forgot about it.
