Package software.amazon.awssdk.services.emr.model

Class Application

  • All Implemented Interfaces:
    Serializable, SdkPojo, ToCopyableBuilder<Application.Builder,​Application>
    @Generated("software.amazon.awssdk:codegen")
public final class Application
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Application.Builder,​Application>

    With Amazon EMR release version 4.0 and later, the only accepted parameter is the application name. To pass arguments to applications, you use configuration classifications specified using configuration JSON objects. For more information, see Configuring Applications.

    With earlier Amazon EMR releases, the application is any Amazon or third-party software that you can add to the cluster. This structure contains a list of strings that indicates the software to use with the cluster and accepts a user argument list. Amazon EMR accepts and forwards the argument list to the corresponding installation script as bootstrap action argument.

    • Method Detail

      • name

        public final String name()

        The name of the application.

        Returns:
        The name of the application.

      • version

        public final String version()

        The version of the application.

        Returns:
        The version of the application.

      • hasArgs

        public final boolean hasArgs()
        For responses, this returns true if the service returned a value for the Args property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • args

        public final List<String> args()

        Arguments for Amazon EMR to pass to the application.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasArgs() method.

        Returns:
        Arguments for Amazon EMR to pass to the application.

      • hasAdditionalInfo

        public final boolean hasAdditionalInfo()
        For responses, this returns true if the service returned a value for the AdditionalInfo property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • additionalInfo

        public final Map<String,​String> additionalInfo()

        This option is for advanced users only. This is meta information about third-party applications that third-party vendors use for testing purposes.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAdditionalInfo() method.

        public final int hashCode()
        Overrides:
        hashCode in class Object

      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
