> HBaseStorage doesn't project correctly
> --------------------------------------
>
> Key: PIG-1870
> URL: https://issues.apache.org/jira/browse/PIG-1870
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.8.0

>
> Projecting columns after {{LOAD}} via {{HBaseStorage}} produces unexpected
> results. This is related to the {{loadKey}} functionality and how the
> {{pushProjection}} method in {{HBaseStorage}} has to offset to build a column
> list that aligns with the tuple (the column list doesn't contain the row key).
> This shift appears to create an inconsistency with the FieldSchema for the
> tuple which results in the wrong tuple value being fetched for a given
> column. I'll attach a patch with unit tests that illustrate the problem.
