Description

Exit code for test jar is 0 despite exception thrown

hadoop jar hadoop-mapreduce-test-0.23.0-SNAPSHOT.jar loadgen -Dmapreduce.job.acl-view -m 18 -r 0 -outKey org.apache.hadoop.io.Text -outValue org.apache.hadoop.io.Text -indir nonexistentdir

This differs from example jar which correctly returns the correct exit code

hadoop jar hadoop-mapreduce-examples-0.23.0-SNAPSHOT.jar wordcount nonexistentdir /outputdir
