To be a little more explicit about the APIs we want this ticket to cover, I 
found 8 APIs that are cluster/cluster-prop related:
 * Create Cluster Prop
 ** Current Form: POST /api/cluster \{"set-property": {...}... }
 ** Desired Form: PUT /api/cluster/properties/propName \{"value": "propVal"}
 ** Spreadsheet Ref: Tab 1, Line 13
 * Update Single (Unnested) Cluster Prop
 ** Current Form: POST /api/cluster \{"set-property": {...}... }
 ** Desired Form: PUT /api/cluster/properties/propName \{"value": "propVal"}
 ** Spreadsheet Ref: Tab 1, Line 15
 * Update (Potentially Nested) Cluster Props (Bulk)
 ** Current Form: POST /api/cluster \{"set-obj-property": {...}... }
 ** Desired Form: PUT /api/cluster/properties \{...}
 ** Spreadsheet Ref: Tab 1, Line 16
 * Delete Cluster Prop
 ** Current Form: POST /api/cluster \{"set-property": {"propName": ""}...}
 ** Desired Form: DELETE /api/cluster/properties/propName
 ** Spreadsheet Ref: Tab 1, Line 17
 * Delete Single Async Status
 ** Current Form: DELETE /api/cluster/command-status/123
 ** Desired Form: DELETE /api/cluster/commands/123
 ** Spreadsheet Ref: Tab 7, Line 10
 * Delete All Async Statuses
 ** Current Form: DELETE /api/cluster/command-status
 ** Desired Form: DELETE /api/cluster/commands
 ** Spreadsheet Ref: Tab 7, Line 11
 * Get Async Command Status
 ** Current Form: GET /api/cluster/command-status/123
 ** Desired Form: GET /api/cluster/commands/123
 ** Spreadsheet Ref: Tab 7, Line 12
 * Create rate-limiter
 ** Current Form: POST /api/cluster \{"set-ratelimiter": {...}... }
 ** Desired Form: POST /api/cluster/ratelimiter \{...}
 ** Spreadsheet Ref: Tab 7, Line 35

Obviously this is a big list. IMO it makes sense to split these up across 
different PRs, doing some small number (i.e. 1 or 2) of APIs per-PR. If anyone 
wants to help chip away at this, just call out which APIs from this list you 
intend to work on and we can parallelize them.

In terms of the steps required, the JIRA comments here and here give some good 
background and step-by-step instructions for switching APIs over to the new 
JAX-RS framework, which is usually helpful or even required as the traditional 
v2 framework doesn't lend itself very readily to RESTful APIs. (Those comments 
describe creating a new API "from scratch", but the steps are still applicable 
to modifying an existing API.) The PR 
[here|https://github.com/apache/solr/pull/1053] also serves as a helpful 
example to work from.

Not all API modifications require the new JAX-RS framework, though it is 
preferred going forward. Instructions for updating APIs using the older, 
traditional v2 framework can be found here, and an example PR can be found 
[here|https://github.com/apache/solr/pull/1061].

> Cosmetic, REST-fulness improvements to v2 cluster and clusterprop APIs

>                 URL: https://issues.apache.org/jira/browse/SOLR-16390
>             Project: Solr
>          Issue Type: Sub-task
>          Components: documentation, v2 API
>    Affects Versions: main (10.0)
>            Reporter: Jason Gerlowski
>            Priority: Major
>
> As mentioned on SOLR-15781, the v2 API currently has an experimental 
> designation, and the community has expressed an interest in using this period 
> to update our v2 endpoints to be more REST-ful and consistent.  The current 
> plan is to follow the specific changes laid out in [this 
> spreadsheet|https://docs.google.com/spreadsheets/d/1HAoBBFPpSiT8mJmgNZKkZAPwfCfPvlc08m5jz3fQBpA/edit?usp=sharing],
>  though of course nothing there is set in stone and there are still warts to 
> be worked out.
> This ticket plans to tackle making the changes required for Solr's "Cluster" 
> and "cluster-prop" APIs.
