org.apache.hcatalog.mapreduce.HCatStorageHandler

All Implemented Interfaces:

HiveStorageHandler

Direct Known Subclasses:

FosterStorageHandler

Deprecated.

Use/modify HiveStorageHandler instead

public abstract class HCatStorageHandler
extends java.lang.Object
implements HiveStorageHandler

The abstract Class HCatStorageHandler would server as the base class for all the storage handlers required for non-native tables in HCatalog.

Method Summary

Modifier and Type	Method and Description
abstract void	configureInputJobProperties(TableDesc tableDesc, java.util.Map<java.lang.String,java.lang.String> jobProperties) Deprecated. 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).
abstract void	configureOutputJobProperties(TableDesc tableDesc, java.util.Map<java.lang.String,java.lang.String> jobProperties) Deprecated. 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).
void	configureTableJobProperties(TableDesc tableDesc, java.util.Map<java.lang.String,java.lang.String> jobProperties) Deprecated.
abstract HiveAuthorizationProvider	getAuthorizationProvider() Deprecated. Returns the implementation specific authorization provider

Method Detail

configureInputJobProperties

public abstract void configureInputJobProperties(TableDesc tableDesc,
                                                 java.util.Map<java.lang.String,java.lang.String> jobProperties)

Deprecated.

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

Parameters:

tableDesc -

jobProperties -

configureOutputJobProperties

public abstract void configureOutputJobProperties(TableDesc tableDesc,
                                                  java.util.Map<java.lang.String,java.lang.String> jobProperties)
