Francis Liu commented on HIVE-2773:
-----------------------------------
Since it's an interface, things will still break not unless they extended
DefaultStorageHandler. In any case will ask user@hive.
> HiveStorageHandler.configureTableJobProperites() should let the handler know
> wether it is configuration for input or output

> HiveStorageHandler.configureTableJobProperties() is called to allow the
> storage handler to setup any properties that the underlying
> inputformat/outputformat/serde may need. But the handler implementation does
> not know whether it is being called for configuring input or output. This
> makes it a problem for handlers which sets an external state. In the case of
> HCatalog's HBase storageHandler, whenever a write needs to be configured we
> create a write transaction which needs to be committed or aborted later on.
> In this case configuring for both input and output each time
> configureTableJobProperties() is called would not be desirable. This has
> become an issue since HCatalog is dropping storageDrivers for SerDe and
> StorageHandler (see HCATALOG-237).
> My proposal is to replace configureTableJobProperties() with two methods:
> configureInputJobProperties()
> configureOutputJobProperties()
> Each method will have the same signature. I cursory look at the code and I
> believe changes should be straighforward also given that we are not really
> changing anything just splitting responsibility. If the community is fine
> with this approach I will go ahead and create a aptch.
