Subject Re: Cannot see MR logs in Hadoop 2.x
Date Wed, 08 Jan 2014 07:32:53 GMT
    Sorry for my rough asking. Refine my question.

    When using hadoop 1.x, I can see the MR job logs under "userlogs"
folder in local file system. But I cannot find the MR log in hadoop 2.x
environment. There is no "userlogs" folder.

    Can anybody tell me where to find the log files?

Kyle
