Subject [jira] [Created] (HADOOP-13021) Hadoop swift driver unit test should use unique directory each run

             Summary: Hadoop swift driver unit test should use unique directory each run
                 Key: HADOOP-13021
                 URL: https://issues.apache.org/jira/browse/HADOOP-13021
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/swift
    Affects Versions: 2.7.2
            Reporter: Chen He
            Assignee: Chen He

Since all "unit test" in swift package are actually functionality test, it requires server's
information in the core-site.xml file. However, multiple unit test runs on difference machines
using the same core-site.xml file will result in some unit tests failure. For example:
In TestSwiftFileSystemBasicOps.java
public void testMkDir() throws Throwable {
    Path path = new Path("/test/MkDir");
    //success then -so try a recursive operation
    fs.delete(path, true);

It is possible that machine A and B are running "mvn clean install" using same core-site.xml
file. However, machine A run testMkDir() first and delete the dir, but machine B just tried
to run fs.delete(path,true). It will report failure. This is just an example. There are many
similar cases in the unit test sets. I would propose we use a unique dir for each unit test
run instead of using "Path path = new Path("/test/MkDir")" for all concurrent runs
