Review Comment:
   Even if Uber has been running for 6+ months, it does not mean the config 
work well for OSS, because while we migrating the Uber patches, many fixes and 
other nuances are introduced, I would suggest we move this change to the next 
release to keep the stability of existing MDT workflow.
