Review comment:
If we need to support a global index, we need to use a single source
across parallelisms as the index store right? How does this distributed state
ensure the consistency of the result? Let's say for the case that we change the
parallelism and restart the job. The keys and parallelism hash mapping were
reorganized.

Review comment:
This looks like a `HoodieRecordLocation` + partition path. Can we extend
from it and put this to hudi-common module?
