Subject [jira] [Commented] (SOLR-6082) Umbrella JIRA for Admin UI and SolrCloud.
Date Sun, 28 Dec 2014 18:26:13 GMT

    [ https://issues.apache.org/jira/browse/SOLR-6082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14259693#comment-14259693

Erick Erickson commented on SOLR-6082:
--------------------------------------

[~shalinmangar] Don't know whether this is getting much of your attention, but see SOLR-5507.
Upayavira is working on moving the admin UI to AngularJS, coordinating the two efforts seems
like A Good Thing....

An open question is how to prioritize this and the work on SOLR-5507. How/when should priority
be given to reproducing the current admin UI which looks at things largely on the basis of
individual nodes with SolrCloud bolted on as opposed to adding SolrCloud-centric features
to the admin UI?

Recording here for posterity, as always the people doing the work are the ones who get to
choose.

> 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.
