> RBF: Admin command to support bulk add of mount points

> Key: HDFS-16978

> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Minor
> Labels: pull-request-available
>
> All state store implementations support adding multiple state store records
> using single putAll() implementation. We should provide new router admin API
> to support bulk addition of mount table entries that can utilize this build
> add implementation at state store level.
> For more than one mount point to be added, the goal of bulk addition should be
> # To reduce frequent router calls
> # To avoid frequent state store cache refreshers with each single mount
> point addition
