My application implements Tool interface and I can submit the job using
shell script "hadoop jar xxx.jar app". But here I don't want to use this
script. Instead, I want to catch errors in my Java code and do some
further proccessings.

Hi,
I used to submit Hadoop job with the utility RunJar.main() on hadoop
0.18. On hadoop 0.19, because the commandLineConfig of JobClient was
null, I got a NullPointerException error when RunJar.main() calls
GenericOptionsParser to get libJars (0.18 didn't do this call). I
also tried the class JobShell to submit job, but it catches all
exceptions and sends to stderr so that I cann't handle the exceptions
myself.
I noticed that if I can call JobClient's setCommandLineConfig method,
everything goes easy. But this method has default package
accessibility, I cann't see the method out of package
org.apache.hadoop.mapred.
Any advices on using Java APIs to submit job?
