弹性搜索集群名称配置

Question

当我运行curl'http://localhost:9200/?pretty'

{
  "name" : "jk5lTpm",
  "cluster_name" : "elasticsearch_neddannocise",
  "cluster_uuid" : "1GV0MUaCS66pPaaYcWkbfg",
  "version" : {
    "number" : "6.2.2",
    "build_hash" : "10a1add",
    "build_date" : "2018-02-16T19:01:30.685723Z",
    "build_snapshot" : false,
    "lucene_version" : "7.2.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

带有neddannocise的“ cluster_name”的值是我加入公司之前我的mac用户的名称。

我在elasticsearch上遇到问题。

我当前的错误错误是

Caused by: java.lang.IllegalStateException: failed to obtain node locks, tried [[/usr/local/var/elasticsearch/elasticsearch_neddannocise]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?

我完成了brew卸载，然后再次安装。

有人知道为什么我的计算机的这个老用户仍然以某种方式与弹性搜索相关吗？如何通过弹性搜索“重新开始”？
