elek opened a new pull request #1002: HDDS-1716. Smoketest results are generated with an internal user
URL: https://github.com/apache/hadoop/pull/1002
 
 
   [~eyang] reported the problem in HDDS-1609 that the smoketest results are generated a user (the user inside the docker container) which can be different from the host user.
   
   There is a minimal risk that the test results can be deleted/corrupted by an other users if the current user is different from uid=1000
   
   I opened this issue because [~eyang] said me during an offline discussion that HDDS-1609 is a more complex issue and not only about the ownership of the test results.
   
   I suggest to handle the two problems in different way. With this patch, the permission of the test result files can be fixed easily.
   
   In HDDS-1609 we can discuss about general security problems and try to find generic solution for them.
   
   Steps to reproduce _this_ the problem:
    # Use a user which is different from uid=1000
    # Create a new ozone build (mvn clean install -f pom.ozone.xml -DskipTests)
    # Go to a compose directory (cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/compose/)
    # Execute tests (./test.sh)
    # check the ownership of the results (ls -lah ./results)
   
   Current result: the owner of the result files are the user uid=1000
   
   Expected result: the owner of the files should be always the current user (even if the current uid is different)
