Subject [jira] [Commented] (MAPREDUCE-3443) Oozie jobs are running as oozie user even though they create the jobclient as doAs.
Date Thu, 01 Dec 2011 20:46:40 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161142#comment-13161142

Hudson commented on MAPREDUCE-3443:

Integrated in Hadoop-Hdfs-trunk-Commit #1425 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk-Commit/1425/])
    MAPREDUCE-3443. JobClient and Job should function in the context of the UGI which created
them. (Contributed by Mahadev Konar)

> Oozie is having issues with job submission, since it does the following:
> {code}
> doAs(userwhosubmittedjob) {
>  jobclient = new JobClient(jobconf);
> }
> jobclient.submitjob()
> {code}
> In 0.20.2** this works because the JT proxy is created as soon as we call new JobClient().
But in 0.23 this is no longer true since the client has to talk to multiple servers (AM/RM/JHS).
To keep this behavior we will have to store the ugi in new JobClient() and make sure all the
calls are run with a doAs() inside the jobclient.
