All Implemented Interfaces:

HiveStorageHandler

Deprecated.

Use/modify FosterStorageHandler instead

public class FosterStorageHandler
extends HCatStorageHandler

This class is used to encapsulate the InputFormat, OutputFormat and SerDe artifacts of tables which don't define a SerDe. This StorageHandler assumes the supplied storage artifacts are for a file-based storage system.

Description copied from class: HCatStorageHandler

This method is called to allow the StorageHandlers the chance to populate the JobContext.getConfiguration() with properties that maybe be needed by the handler's bundled artifacts (ie InputFormat, SerDe, etc). Key value pairs passed into jobProperties is guaranteed to be set in the job's configuration object. User's can retrieve "context" information from tableDesc. User's should avoid mutating tableDesc and only make changes in jobProperties. This method is expected to be idempotent such that a job called with the same tableDesc values should return the same key-value pairs in jobProperties. Any external state set by this method should remain the same if this method is called again. It is up to the user to determine how best guarantee this invariant. This method in particular is to create a configuration for input.

Specified by:

configureInputJobProperties in interface HiveStorageHandler

Specified by:

configureInputJobProperties in class HCatStorageHandler

Parameters:

tableDesc - descriptor for the table being accessed

jobProperties - receives properties copied or transformed from the table properties

configureOutputJobProperties

                                         java.util.Map<java.lang.String,java.lang.String> jobProperties)

Deprecated.
