Review comment:
Okay my bad. can we pull this into a static final variable for now.

Review comment:
the stats are important, so let's keep it there. I think this happens
because some parts of the tests run with metadata enabled and this is returned
as the fallback. If its not too many, can we fix the tests. it does not make
sense to have this return `false` semantically.

Review comment:
Can we add more tests to this piece of code? (previously it was just in
the bootstrap part), not this is prime time.

Review comment:
On a side note, we should move it to the hudi-hadoop-mr module or rename
this to `HoodieLocalEngine` or something. Lets discuss the relocation in the
other comment.
