Re: Automate startup/shutdown of SolrCloud Shards
I could use an easier way to do this myself:
https://issues.apache.org/jira/browse/SOLR-2805
I'm going to add a main method to ZkController that will make this simpler -
I've got an early version that works something like: java -classpath .:*
org.apache.solr.cloud.ZkController 127.0.0.1:9983 127.0.0.1 8983 solr
/home/mark/workspace/SolrCloud/solr/example/solr/conf conf1

Re: Automate startup/shutdown of SolrCloud Shards

Something like this would be excellent. Right now I am starting up
the main server and then doing a wget to see if the server has started
successfully before firing off any secondary servers. If we could do
what you're saying then everything is much cleaner to do.
