Robert Kanter created MAPREDUCE-6550: ----------------------------------------
Summary: archive-logs tool changes log ownership to the Yarn user when using DefaultContainerExecutor Key: MAPREDUCE-6550 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6550 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 2.8.0 Reporter: Robert Kanter Assignee: Robert Kanter The archive-logs tool added in MAPREDUCE-6415 leverages the Distributed Shell app. When using the DistributedContainerExecutor, this means that the job will actually run as the Yarn user, so the resulting har files are owned by the Yarn user instead of the original owner. The permissions are also now world-readable. In the below example, the archived logs are owned by 'yarn' instead of 'paul' and are now world-readable: {noformat} [root@gs28-centos66-5 ~]# sudo -u hdfs hdfs dfs -ls -R /tmp/logs ... drwxrwx--- - paul hadoop 0 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005 drwxr-xr-x - yarn hadoop 0 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005/application_1443805425363_0005.har -rw-r--r-- 3 yarn hadoop 0 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005/application_1443805425363_0005.har/_SUCCESS -rw-r--r-- 3 yarn hadoop 1256 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005/application_1443805425363_0005.har/_index -rw-r--r-- 3 yarn hadoop 24 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005/application_1443805425363_0005.har/_masterindex -rw-r--r-- 3 yarn hadoop 8451177 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0005/application_1443805425363_0005.har/part-0 drwxrwx--- - paul hadoop 0 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0006 -rw-r----- 3 paul hadoop 1155 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0006/gs-centos66-2.vpc.cloudera.com_8041 -rw-r----- 3 paul hadoop 4880 2015-10-02 13:24 /tmp/logs/paul/logs/application_1443805425363_0006/gs28-centos66-3.vpc.cloudera.com_8041 ... {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
