Class Configuration

java.lang.Object

com.amazonaws.services.elasticmapreduce.model.Configuration

All Implemented Interfaces:

Serializable, Cloneable

public class Configuration
extends Object
implements Serializable, Cloneable

NOTE: Amazon EMR releases 4.x or later.

Specifies a hardware and software configuration of the EMR cluster. This includes configurations for applications and software bundled with Amazon EMR. The Configuration object is a JSON object which is defined by a classification and a set of properties. Configurations can be nested, so a configuration may have its own Configuration objects listed.

Method Detail

getClassification

public String getClassification()

The classification of a configuration. For more information see, Amazon EMR Configurations.

Returns:

The classification of a configuration. For more information see, Amazon EMR Configurations.

setClassification

public void setClassification(String classification)

The classification of a configuration. For more information see, Amazon EMR Configurations.

Parameters:

classification - The classification of a configuration. For more information see, Amazon EMR Configurations.

withClassification

public Configuration withClassification(String classification)

The classification of a configuration. For more information see, Amazon EMR Configurations.

Returns a reference to this object so that method calls can be chained together.

Parameters:

classification - The classification of a configuration. For more information see, Amazon EMR Configurations.

Returns:

A reference to this updated object so that method calls can be chained together.

getConfigurations

public List<Configuration> getConfigurations()

A list of configurations you apply to this configuration object.

Returns:

setConfigurations

public void setConfigurations(Collection<Configuration> configurations)

A list of configurations you apply to this configuration object.

Parameters:

configurations - A list of configurations you apply to this configuration object.

withConfigurations

public Configuration withConfigurations(Configuration... configurations)

A list of configurations you apply to this configuration object.

NOTE: This method appends the values to the existing list (if any). Use setConfigurations(java.util.Collection) or withConfigurations(java.util.Collection) if you want to override the existing values.

Returns a reference to this object so that method calls can be chained together.

Parameters:

configurations - A list of configurations you apply to this configuration object.

Returns:

A reference to this updated object so that method calls can be chained together.

withConfigurations

public Configuration withConfigurations(Collection<Configuration> configurations)

A list of configurations you apply to this configuration object.

Returns a reference to this object so that method calls can be chained together.

Parameters:

configurations - A list of configurations you apply to this configuration object.

Returns:

A reference to this updated object so that method calls can be chained together.

getProperties

public Map<String,String> getProperties()

A set of properties supplied to the Configuration object.

Returns:

A set of properties supplied to the Configuration object.

setProperties

public void setProperties(Map<String,String> properties)

A set of properties supplied to the Configuration object.

Parameters:

properties - A set of properties supplied to the Configuration object.

withProperties

public Configuration withProperties(Map<String,String> properties)

A set of properties supplied to the Configuration object.

Returns a reference to this object so that method calls can be chained together.

Parameters:

properties - A set of properties supplied to the Configuration object.

A set of properties supplied to the Configuration object.

The method adds a new key-value pair into Properties parameter, and returns a reference to this object so that method calls can be chained together.

Parameters:

key - The key of the entry to be added into Properties.

value - The corresponding value of the entry to be added into Properties.

clearPropertiesEntries

public Configuration clearPropertiesEntries()

Removes all the entries added into Properties.

Returns a reference to this object so that method calls can be chained together.
