快递提取：分片失败 [英] Courier Fetch: shards failed

问题描述

为什么在向弹性搜索添加更多数据后会收到这些警告？
每次浏览仪表板时，警告都不同。

Why do I get these warnings after adding more data to my elasticsearch? And the warnings are different every time I browse the dashboard.

Courier Fetch：60个分片中的30个失败。

"Courier Fetch: 30 of 60 shards failed."

        "mlockall" : false
      }
    }
  }
}

我很好奇mlockall：false 因为在yml我写了 bootstrap.mlockall：true

I'm curious about the "mlockall" : false because on the yml I did write bootstrap.mlockall: true

日志

很多行如：

org.elasticsearch.common.util.concurrent.EsRejectedExecutionException: rejected execution (queue capacity 1000) on org.elasticsearch.search.action.SearchServiceTransportAction$23@a9a34f5

推荐答案

这可能表明您的群集健康有问题。不了解更多关于您的群集，没有更多的可以说。

This is likely an indication that there's a problem with your cluster's health. Without knowing more about your cluster, there's not much more that can be said.
