This pull request was never merged because of a problem with windows test
setup we have. As a workaround, I added code to fall back to using old API if
new API fails for some reason. All tests are passing fine with this change.
This is nice to include in 1.12 as it provides performance improvement for
all DFS based queries especially when there are large number of files.
Can we review the new diffs please ?---
