---------------------------------

             Summary: TeraGen Application allows same output directory for multiple jobs 
                 Key: YARN-4383
                 URL: https://issues.apache.org/jira/browse/YARN-4383
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: tongshiquan


When Teragen is run multiple times with the same output directory, normally it should validate  and fail.

But some cases it may continue and cause the exceptions which results failure in job later time.


I think the reason behind it is 
{code} org.apache.hadoop.examples.terasort.TeraOutputFormat.checkOutputSpecs(TeraOutputFormat.java) have issue, it permit the output already exists if it have only 1 kid and it's PARTITION_FILENAME
{code}
