Shawn Heisey commented on SOLR-4450:
------------------------------------
I just had another thought. One problem with using solr.xml for the zookeeper
information is that the cores are also stored there, so you cannot just copy it
from an existing host to a new one. I think it would be a good idea to use a
separate config file for the zookeeper information, with a fallback to solr.xml.
> Developer Curb Appeal: Need consistent command line arguments for all nodes

> Key: SOLR-4450
> URL: https://issues.apache.org/jira/browse/SOLR-4450
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.1
> Reporter: Mark Bennett
> Fix For: 4.2
>
>
> Suppose you want to create a small 4 node cluster (2x2, two shards, each
> replicated), each on it's own machine.
> It'd be nice to use the same script in /etc/init.d to start them all, but
> it's hard to come up with a set of arguments that works for both the first
> and subsequent nodes.
> When MANUALLY starting them, the arguments for the first node are different
> than for subsequent nodes:
> Node A like this:
> -DzkRun -DnumShards=2 -Dbootstrap_confdir=./solr/collection1/conf
> -Dcollection.configName=MyConfig -jar start.jar
> Vs. the other 3 nodes, B, C, D:
> -DzkHost=nodeA:9983 -jar start.jar
> But if you combine them, you either still have to rely on Node A being up
> first, and have all nodes reference it:
> -DzkRun -DzkHost=nodeA:9983 -DnumShards=2
> -Dbootstrap_confdir=./solr/collection1/conf -Dcollection.configName=MyConfig
> OR you can try to specify the address of all 4 machines, in all 4 startup
> scripts, which seems logical but doesn't work:
> -DzkRun -DzkHost=nodeA:9983,nodeB:9983,nodeC:9983,nodeD:9983
> -DnumShards=2 -Dbootstrap_confdir=./solr/collection1/conf
> -Dcollection.configName=MyConfig
> This gives an error:
> org.apache.solr.common.SolrException log
> SEVERE: null:java.lang.IllegalArgumentException: port out of range:-1
> This thread suggests a possible change in syntax, but doesn't seem to work
> (at least with the embedded ZooKeeper)
> Thread:
> http://lucene.472066.n3.nabble.com/solr4-0-problem-zkHost-with-multiple-hosts-throws-out-of-range-exception-td4014440.html
> Syntax:
> -DzkRun -DzkHost=nodeA:9983,nodeB:9983,nodeC:9983,nodeD:9983/solrroot
> -DnumShards=2 -Dbootstrap_confdir=./solr/collection1/conf
> -Dcollection.configName=MyConfig
> Error:
> SEVERE: Could not start Solr. Check solr/home property and the logs
> Feb 12, 2013 1:36:49 PM org.apache.solr.common.SolrException log
> SEVERE: null:java.lang.NumberFormatException: For input string:
> "9983/solrroot"
> at
> java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
> So:
> * There needs to be some syntax that all nodes can run, even if it requires
> listing addresses (or multicast!)
> * And then clear documentation about suggesting external ZooKeeper to be used
> for production (list being maintained in SOLR-4444)
