   needs to disable caching for that fs or this can pick up existing one from cache

Review Comment:
   use LambdaTestUtils.intercept(); return the actual FileSystem.toString() in the error, e.g
   ```java
   intercept(IllegalArgument.class, "should extend", () -> 
     "got filesystem " + FileSystem.getLocal(conf));
   ```
