Description

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"); fs.mkdirs(path); //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
