一、确认问题

1.   elasticsearch节点启动失败
2.   elasticsearch节点集群日志中有如下报错

Jul 19 18:24:46 mon02 elasticsearch[55262]: org.elasticsearch.bootstrap.StartupException: org.elasticsearch.common.inject.CreationException: Guice creation errors:

二、处理办法

问题原因

    上述问题原因是该es节点在运行期间被强制终止运行，包括不限于 断电、断网、强制主机重启、kill -9等错误的操作方式。

处理办法

    关闭该es节点，删除报错中提示路径下的/data/elasticsearch/data/nodes/0/indices/FHG3Q6zcT56F23WGkwR6bg/_state/state-272.st文件，重启该es节点即可正常运行。
