tongshiquan created YARN-4383: --------------------------------- 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} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
