------------------------------------
HIVE-17373 is the jira that I'm trying to upgrade accumulo to 1.8.1. I just
uploaded a new patch, but I tested this patch locally and noticed that we are
hitting this NPE issue with the same stack trace.
> 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.
