----------------------------------------
Just a note: if zookeeper is unavailable new ui freezes for a long time and
then respond with \{\{placehoders}}. Old UI is musch responsive in such
disaster.
> Umbrella JIRA for Admin UI and SolrCloud.
> -----------------------------------------
>
> Key: SOLR-6082
> URL: https://issues.apache.org/jira/browse/SOLR-6082
> Project: Solr
> Issue Type: Improvement
> Components: web gui
> Affects Versions: 4.9, 6.0
> Reporter: Erick Erickson
> Assignee: Erick Erickson
>
> It would be very helpful if the admin UI were more "cloud friendly". This is
> an umbrella JIRA so we can collect sub-tasks as necessary. I think there
> might be scattered JIRAs about this, let's link them in as we find them.
> [~steffkes] - I've taken the liberty of assigning it to you since you
> expressed some interest. Feel free to assign it back if you want...
> Let's imagine that a user has a cluster with _no_ collections assigned and
> start from there.
> Here's a simple way to set this up. Basically you follow the reference guide
> tutorial but _don't_ define a collection.
> 1> completely delete the "collection1" directory from example
> 2> cp -r example example2
> 3> in example, execute "java -DzkRun -jar start.jar"
> 4> in example2, execute "java -Djetty.port=7574 -DzkHost=localhost:9983 -jar
> start.jar"
> Now the "cloud link" appears. If you expand the tree view, you see the two
> live nodes. But, there's nothing in the graph view, no cores are selectable,
> etc.
> First problem (need to solve before any sub-jiras, so including it here): You
> have to push a configuration directory to ZK.
> [~thetapi] The _last_ time Stefan and I started allowing files to be written
> to Solr from the UI it was...unfortunate. I'm assuming that there's something
> similar here. That is, we shouldn't allow pushing the Solr config _to_
> ZooKeeper through the Admin UI, where they'd be distributed to all the solr
> nodes. Is that true? If this is a security issue, we can keep pushing the
> config dirs to ZK a manual step for now...
> Once we determine how to get configurations up, we can work on the various
> sub-jiras.
