Review comment:
This enables auto-translation from Azure's Object IDs (OIDs) to the Linux
username. Failure to do this causes problems with running mapred jobs (bulk
ingest) using ADLS Gen 2 as the storage for the RFiles. In parallel
@karthick-rn has a [PR](https://github.com/apache/hadoop/pull/1785) on the
Hadoop repo to document this setting.
