hi all,
since the new elk version (elasticsearch 2.0,kibana 4.2.1 and logstash2.0) released,i removed the olded elk version(logstash 1.5,elasticsearch 1.5 and kibana 4.0). However,after i installed new version,i can't open the localhost:9200 in browser,and logstash can't insert events into elasticsearch.
PS. i can retrieve the cluster health status with curl 'localhost:9200/_cat/health?v' command
