[jira] Resolved: (HADOOP-1102) Setting speculative execution to false via setSpeculativeExecution(false) doesn't seem to have effect

Posted by "Owen O'Malley (JIRA)" <ji...@apache.org>.

Owen O'Malley resolved HADOOP-1102.
-----------------------------------

    Resolution: Duplicate

I believe this was caused by setting the speculative execution to true in hadoop-site.xml, which overrides the application's settings. That will be addressed by fixing the config system in HADOOP-785.
