public class HadoopConfiguration
extends AbstractStandalone

The Hadoop setup, used by other Hadoop actors.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: HadoopConfiguration
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default: 
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded 
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-conf <adams.core.io.PlaceholderDirectory> (property: configuration)
    The directory with the Hadoop configuration to use.
    default: conf
 

-bin <adams.core.io.PlaceholderDirectory> (property: binaries)
    The directory with the Hadoop binaries to use.
    default: bin
