Review Comment:
> @Zouxxyy then we need a different way to load the default conf file and
set it as the expected value. the current way is not the right way for testing:
both expected and tested use `DFSPropertiesConfiguration` to load. what if
there is a bug with `DFSPropertiesConfiguration` loading conf file and both
return unexpected numbers, the test would still pass but not catching bug
I made some modifications.
I think this test case is only used to test the effect of clearing env
HUDI_CONF_DIR, so the test can be ignored when hudi-defaults.conf exists
locally.
And if you want to test loading hudi-defaults.conf, it should be covered by
other tests, such as testParsing, testLoadGlobalConfFile, etc.
