Subject Solr Admin UI and SolrCloud
Date Mon, 12 May 2014 16:58:21 GMT
The admin UI (and kudos to _everyone_ who made the new version) could
use more "cloud awareness". There are cluster-wide operations and
individual node operations, they're intermixed at this point. Plus, we
make people switch between a UI and the command-line to accomplish
what they need to.

How can we restructure them? And should we?

Straw-man proposal follows. NOTE: I have no real attachment to this
layout, just looking to generate a discussion!

The rest of the points are really for the cloud-specific page

adding nodes, all that stuff.

node on a particular machine

for a particular shard, with drop-down lists showing available collections, available shards
and even suggesting a name for it and all that kind of thing.

file uploads from being a problem?
