我是Elasticsearch的新手。我在本地仅运行一个节点。到现在为止一切正常。现在,它一开始就崩溃了。错误堆栈如下。

我对Elasticsearch
6.3有同样的问题。我下载了6.5.1,它在一段时间内运行良好。但是,这再次发生了。一段时间后,我必须主持Elasticsearch。请帮助我解决问题。
我遇到了几乎相同的情况,并尝试将损坏的索引移至/ tmp
/目录并重新启动了计算机。重新启动后(我已经设置了Elasticsearch以在重新启动后自动运行)后一切正常。
因此,根据您的情况,这里是解决方案:1)将文件/整个索引目录移动到其他位置C:\ MyApps \ elasticsearch6.5.1 \
elasticsearch-oss-6.5.1 \ elasticsearch-6.5.1 \ data \ nodes \ 0 \ indices \
0gZa7OvBS4GaYgFeY2sKaQ_state \ state-153.st
2)然后重启机器
3)重新启动elasticsearch流程(如果未在crontab或Scheduler中添加)
4)就这样!
祝好运
