Subject [jira] Commented: (HADOOP-5260) streaming failed without printing out the cause (IllegalArgumentException)
Date Fri, 13 Feb 2009 23:36:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673420#action_12673420
] 

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.
