Hello Tom,
But could I also use the new API by doing this?:
Configuration configuration = new Configuration();
Cluster cluster = new Cluster(configuration);
Job job = Job.getInstance(cluster);
...
System.exit(job.waitForCompletion(true) ? 0 : 1);
If I do this I get the most peculiar error, telling me:
java.lang.NoSuchMethodError:
org.apache.hadoop.conf.Configuration.addDeprecation(Ljava/lang/String;[Ljava/lang/String;)V
I looked into the source and this method does exist. I did use the
precomiled version of the jar files coming with the downloadable
MapReduce package.

Note that JobClient, along with the rest of the "old" API in
org.apache.hadoop.mapred, has been undeprecated in Hadoop 0.21.0 so
you can continue to use it without warnings.

In 0.21, JobClient methods are available in org.apache.hadoop.mapreduce.Job

Hello,
I am using the Hadoop MapReduce version 0.20.2 and soon 0.21.
I wanted to use the JobClient class to circumvent the use of the command
line interface.
I am noticed that JobClient still uses the deprecated JobConf class for
jib submissions.
Are there any alternatives to JobClient not using the deprecated JobConf
class?
Thanks in advance,
Martin
