Subject [jira] [Created] (HADOOP-12131) The different JDKs which versions are the same aren't distiguished on multi-JDK mode
Date Sat, 27 Jun 2015 15:01:04 GMT
Kengo Seki created HADOOP-12131:
-----------------------------------

             Summary: The different JDKs which versions are the same aren't distiguished on
multi-JDK mode
                 Key: HADOOP-12131
                 URL: https://issues.apache.org/jira/browse/HADOOP-12131
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: yetus
    Affects Versions: HADOOP-12111
            Reporter: Kengo Seki


If one installs the same version of Oracle JDK and OpenJDK and enables the multi-JDK option,
output files are overwritten by the last one because the same value is assigned to $jdk and
$fn. Example:
