Robert Kanter commented on MAPREDUCE-4942: ------------------------------------------ Looking at this some more, it seemed that {{cluster.getClient().getJobStatus}} was the issue. Its signature in the {{ClientProtocol}} interface throws the {{InterruptedException}}, but none of its implementations seem to actually throw this exception. However, {{ugi.doAs}} is also throwing the {{InterruptedException}} and I'd be more reluctant to change this because its used all over the place. > mapreduce.Job has a bunch of methods that throw InterruptedException so its > incompatible with MR1 > ------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-4942 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4942 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 2.0.2-alpha > Reporter: Robert Kanter > Assignee: Robert Kanter > > 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}}. > {code} > 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 > {code} -- This message is automatically generated by JIRA.
