Solr's clusterstate.json cleaner

If solrcloud is running with autoscale cluster enabled, there may be lots of "gone" nodes in clusterstate.json.

This program cleans those 'gone' nodes out of the clusterstate.json.

Build and dockerize

mvn clean package
docker build . -t solr-clusterstate-cleaner:0.1.0

Running with docker

The program requires only one argument which is solr path in zookeeper. You may need to change zookeeper host using the "wongnai.solr.zk.host" property.

docker run --rm solr-clusterstate-cleaner:0.1.0 --wongnai.solr.zk.host=172.17.0.1:2181 /wongnai/solr
