Class HadoopJarStepConfig
- All Implemented Interfaces:
Serializable
,SdkPojo
,ToCopyableBuilder<HadoopJarStepConfig.Builder,
HadoopJarStepConfig>
A job flow step consisting of a JAR file whose main function will be executed. The main function submits a job for Hadoop to execute and waits for the job to finish or fail.

Method Details
-
hasProperties
public final boolean hasProperties()For responses, this returns true if the service returned a value for the Properties property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
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. -
properties
A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.
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
hasProperties()
method.- Returns:
- A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.
-
jar
A path to a JAR file run during the step.
- Returns:
- A path to a JAR file run during the step.
-
mainClass
The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.
- Returns:
- The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.
-
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 theisEmpty()
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
A list of command line arguments passed to the JAR file's main function when executed.
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:
- A list of command line arguments passed to the JAR file's main function when executed.

toBuilder
Description copied from interface:ToCopyableBuilder
Take this object and create a builder that contains all of the current property values of this object.- Specified by:

in interfaceToCopyableBuilder<HadoopJarStepConfig.Builder,

- a builder for type T

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
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. -
