Subject [jira] [Commented] (HADOOP-11733) mvn clean does not clean /tmp
Date Fri, 20 Mar 2015 16:30:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14371576#comment-14371576

Sean Busbey commented on HADOOP-11733:
--------------------------------------

Can we move these writes to be within a target directory instead?

It's maven best practice to avoid writing out side of the build directory. It'll also do a
better job of e.g. allowing us to run tests in parallel.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-11733
>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.6.0
>         Environment: All
>            Reporter: Tony Reix
>            Priority: Minor
>
> When Hadoop tests are run, files and directories are created in /tmp .
> Many (or all) of them are not cleaned when running "mvn clean".
> This generates an issue when tests were previously run (by mistake) as root and then
run again as a non-root user, since directories (like: .hdfs-nfs hadoop-root hsperfdata_root)
cannot be written by second test run.
> List of files/directories that seem to be created in /tmp when testing Hadoop:
>    Jetty* *test *deferred .hdfs-nfs hadoop-root hsperfdata_root
> and that should be cleaned after tests.
