[WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler]  uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: failed to obtain node locks, tried [[/opt/elasticsearch-5.5.0/data/elasticsearch]] with lock id ; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was )?
