Sushanth Sowmyan commented on HIVE-6936:
----------------------------------------
Looking into it. Will provide a quick description of how it's handled in HCat:
In HCat, we pass along tableProperties using
HiveStorageHandler.configureInputJobProperties and
HiveStorageHandler.configureOutputJobProperties. HBaseSH sees only this.
To standardize usage across all IF/OF cases, we have a storage handler called
FosterStorageHandler that acts as a wrapper around the generic IF/OF cases that
do not have storage handlers, so that the rest of the HCat code can still stick
to using StorageHandlers as-is and not worry about the underlying system.
To make FosterStorageHandler work with orc, we had to change orc so it accepted
table property overrides from jobconf as well (since we have to conform to
mapreduce interfaces only, and that has no knowledge of tables), and had
FosterStorageHandler set up jobconf appropriately with any overrides from table
properties.

> Some advanced file formats need the table properties made available to them.
> Additionally, it would be convenient to provide a unique id for fetch
> operators and the complete list of directories.
