Koji Noguchi commented on HADOOP-5260:
--------------------------------------
Looking at StreamJob.java
{noformat}
131 preProcessArgs();
132 parseArgv();
133 postProcessArgs();
134
135 setJobConf();
136 return submitAndMonitorJob();
137 }catch (IllegalArgumentException ex) {
138 //ignore, since log will already be printed
139 return 1;
140 }
{noformat}
seems like IllegalArgumentException info is not printed when it's thrown from
mapred (non-streaming) framework.
> streaming failed without printing out the cause (IllegalArgumentException)
