- oracle.kv.hadoop.hive.table.TableTaskAttemptContext

All Implemented Interfaces:

JobContext, MRJobConfig, TaskAttemptContext, Progressable
```
public class TableTaskAttemptContext
extends Object
implements TaskAttemptContext
```
Concrete implementation of Hadoop TaskAttemptContext interface. When initializing a YARN based (MapReduce version 2) RecordReader, an instance of TaskAttemptContext must be specified. This class is intended to satisfy that requirement. Note that the RecordReader provided for Hadoop integration is YARN based, whereas the Hive infrastructure requires a RecordReader based on version 1 MapReduce. To address this incompatibility when integrating with HIVE, a version 1 based RecordReader is used, but wraps and delegates to a version 2 RecordReader; thus, the need for this class. Currently, the methods of this class are "stubbed out" and/or return default values; which seems to be acceptable for the Hive integration.

  - getArchiveClassPaths
```
public Path[] getArchiveClassPaths()
```
    Specified by JobContext interface (TaskAttemptContext extends JobContext). Note that whereas it would be preferrable to define this class to implement TaskAttemptContext and extend the Job class (so that this class inherits the implementations of all of the methods defined below), that cannot be done. This is because the Job class implements the method JobStatus getStatus, while the TaskAttemptContext interface specifies the method String getStatus. As a result, a sub-class of Job cannot implement TaskAttemptContext; because a method implementation that satisfies the getStatus specification in TaskAttemptContext cannot override the implementation of getStatus provided by Job.
