Class LoggedTask

java.lang.Object
  org.apache.hadoop.tools.rumen.LoggedTask

All Implemented Interfaces:

DeepCompare

Direct Known Subclasses:

ParsedTask

public class LoggedTask
extends Object
implements DeepCompare

A LoggedTask represents a [hadoop] task that is part of a hadoop job. It knows about the [pssibly empty] sequence of attempts, its I/O footprint, and its runtime. All of the public methods are simply accessors for the instance variables we want to write out in the JSON files.

deepCompare

public void deepCompare(DeepCompare comparand,
                        TreePath loc)
                 throws DeepInequalityException

Specified by:

deepCompare in interface DeepCompare

Parameters:

comparand - the other comparand that's being compared to me

loc - the path that got to me. In the root, myLocation is null. To process the scalar foo field of the root we will make a recursive call with a TreePath whose fieldName is "bar" and whose index is -1 and whose parent is null. To process the plural bar field of the root we will make a recursive call with a TreePath whose fieldName is "foo" and whose index is -1 and whose parent is also null.

Throws:

DeepInequalityException
