] 

Robert Kanter commented on YARN-7622:
-------------------------------------

Overall looks good.  Just one trivial comment:
- We should add s3 and viewfs to the list of allowed filesystems.

> The FairScheduler requires the allocation file to be hosted on the local filesystem on
the RM node(s). Allowing HDFS to store the allocation file will provide improved redundancy,
more options for scheduler updates, and RM failover consistency in HA.
