Description

The following methods in MR2's org.apache.hadoop.mapreduce.Job throw an InterruptedException but don't in MR1, which makes them incompatible. (Their Javadoc comments are also missing that they throw an InterruptedException anyway)

I propose that we wrap the InterruptedException in a RuntimeException.

public float setupProgress() throws IOException, InterruptedException
public float mapProgress() throws IOException, InterruptedException
public float reduceProgress() throws IOException, InterruptedException
public boolean isComplete() throws IOException, InterruptedException
public boolean isSuccessful() throws IOException, InterruptedException
public void killJob() throws IOException, InterruptedException
public void killTask(org.apache.hadoop.mapreduce.TaskAttemptID) throws IOException, InterruptedException
public void failTask(org.apache.hadoop.mapreduce.TaskAttemptID) throws IOException, InterruptedException
public Counters getCounters() throws IOException, InterruptedException
