org.elasticsearch.xpack.monitoring.exporter.ExportException: exporters are either not ready or faulty    at org.elasticsearch.xpack.monitoring.exporter.Exporters.export(Exporters.java:188) ~[x-pack-5.0.2.jar:5.0.2]    at org.elasticsearch.xpack.monitoring.AgentService$ExportingWorker.run(AgentService.java:208) [x-pack-5.0.2.jar:5.0.2]    at java.lang.Thread.run(Thread.java:745) [?:1.8.0_111]

解决方案：需要将复制的elasticsearch文件夹下data文件中的节点数据清空即可解决该错误
