Github user shijinkui commented on the issue:

    https://github.com/apache/flink/pull/3190
  
    " /tmp/cacheFile (Permission denied)" exception of unit test can be replay.
    
    1. on linux env, `sudo - userA`, clone the flink code, start to `mvn clean test verify`
    2. on the linux machine, `sudo - userB`, clone the flink codebase, same start to `mvn
clean test verify`
    
    Because two use share the same  `/tmp` directory which have no random sub directory.
    IMO, `/tmp` change to `${project.build.directory}`, at same time have random suffix. This
can resolve the problem thoroughly.
