Íñigo Goiri commented on HDFS-12577:
------------------------------------
For the last few months, we've been getting feedback about the naming issues.
I'd like to use this JIRA to cover these.
I'd like to summarize the different comments:
* [~zhz] and [~shv] were concerned about distinguishing it from regular HDFS
federation.
* [~manojg] similarly thought the command line to manage the mount table could
get confusing as it currently used {{hdfs federation}}..
* [~aw] brought up the confusion of having two daemons (in YARN and HDFS)
called {{Router}}.
>From this feedback, I propose the following:
* Referring to this effort as "Router-Based Federation" or RBF.
* Create a class called {{HdfsRouter}} to start the Router, so the current main
from Router would move here. The command would still be {{hdfs router}} but it
would start {{HdfsRouter}} and avoid conflicts when calling {{jps}} etc.
* Rename the command I added for HDFS-10467 from {{hdfs federation}} to {{hdfs
routeradmin}}. Alternatively, I could merge both the Router start and the admin
into {{hdfs router}} and call {{HdfsRouter}} and {{RouterAdmin}} internally.
Thoughts?

> Currently the naming for Router Based Federation has a couple conflicts:
> * Both YARN and HDFS have a Router component which may cause issues for the
> PID file and JPS.
> * The tool to manage the mount table is called using {{hdfs federation}}.
> This may cause confusion with the regular HDFS federation.
