LoggedTaskAttempt (Hadoop 1.2.2-SNAPSHOT API)

java.lang.Object
- org.apache.hadoop.tools.rumen.LoggedTaskAttempt

所有已实现的接口:

DeepCompare

直接已知子类:

ParsedTaskAttempt
```
public class LoggedTaskAttempt
extends Object
implements DeepCompare
```
A LoggedTaskAttempt represents an attempt to run an hadoop task in a hadoop job. Note that a task can have several attempts. All of the public methods are simply accessors for the instance variables we want to write out in the JSON files.

指定者:

deepCompare 在接口中 DeepCompare

参数:
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.

抛出:

DeepInequalityException
