Solr Cloud - How to maintain the addresses of the zookeeper servers

2017-01-26 Thread David Michael Gang
Hi all,

I want to set up a solr cloud with x nodes and have 3 zookeepers servers.
As i understand the following parties need to know all zookeeper servers:
* All zookeeper servers
* All solr cloud nodes
* All solr4j cloud smart clients

So let's say if i make it hard coded and then want to add 2 zookeeper
nodes, I would have to update many places. This makes it hard to maintain
it.
How do you manage this? Is there a possibility to get the list of zookeeper
services dynamically? Any other idea?
I wanted to hear from your expereince how to achieve this task effectively.

Thanks,
David

Hi Markus and Jan,

Thanks for the quick response and good ideas.
I will look for the puppet direction. We already use puppet, so this is
easy to add

Thanks a lot,
David

minimal solrconfig example

2017-03-01 Thread David Michael Gang
Hi all,

I want to create my first solr collection
I found an example of solrconfig here.
https://github.com/apache/lucene-solr/blob/master/solr/example/files/conf/solrconfig.xml
This is a file of more than thousand lines.
As i understand this file shows all possible configurations possible.
What i miss is the most minimal file.
Where i can i find a minimal solrconfig.xml file with just the required
options?

Thanks,
David

Hi David,

What is the solr version you are using?
To get started, it's better to use the config file that comes out of the
box.

Thanks,
