Problems with loading core when starting Solr 5.2.1
Hi,
I've just migrated to Solr 5.2.1 with external ZooKeeper 3.4.6.
Whenever I tried to start Solr using these command, the Solr servers gets
started, but none of the cores is actually loaded.
- bin\solr.cmd start -cloud -z localhost:2181
- bin\solr.cmd -cloud -p 8983 -s server\solr -z localhost:2181
I can only get the core to be loaded when I use the following command
- bin\solr.cmd -e cloud -z localhost:2181
However, this command is actually the step by step guide to create a new
collection, and I don't have to create a new collection each time I start
Solr.
Is there anything wrong with my first two commands?
Regards,
Edwin

Hi, Would Solr give inconsistent results if ZK quorum not achieved + one leader (last state) goes down?

Yes, it shows the following under 'args'.
- -DzkHost=localhost:2181,localhost:2182,localhost:2183

If the zookeeper used isnt visible via the ui, it should be. Does it
show on the main dashboard under 'args'?

Thanks Erick for the info.
So mine should be running on external ZooKeeper, since I'm using "-
bin\solr.cmd
-e cloud -z localhost:2181" and not -DzkRun, and Solr is able to read the
updated the configuration after I update it in the external ZooKeeper.

Edwin

A Zookeeper quorum is not necessary for searching. Well,
that's stating it a little too strongly. A Solr cluster will do its
best to search given the last state of the cluster each
Solr node got from Zookeeper.
You will not be able to index without a quorum though.
bq: How do I check if my Solr is running based on the external ZooKeeper or the
embedded ZooKeeper in Solr 5.2.1?
You have to specify the -DzkRun to run embedded ZK. If you didn't do that,
it's not running.
Best,
Erick

How do I check if my Solr is running based on the external ZooKeeper or the
embedded ZooKeeper in Solr 5.2.1?
Currently I can still do a search even though I've shut down 2 out of 3
ZooKeeper. Only the Cloud tab is down, but the rest of the search are still
working.

After you have created the cloud example, you need different commands to
restart or start those nodes. See the "Restarting Nodes" section of
this page for some help with doing this:

Use bin/solr create to make a new collection.
