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
Reporter: Bill Graham
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.
