java - 将数据加载到 Druid 时出错

问题描述

我是 druid 新手，试图通过本地文件加载数据。我已经设置了节点和 zookeeper 实例。我在 Ubuntu 18.04 中尝试过这个并且工作正常，但我尝试在 lUbuntu 中使用它，我看到以下错误：

我确实尝试增加中层管理人员的内存，假设这是导致问题的原因，但没有奏效。任何帮助，将不胜感激。谢谢 ！

解决方案

我认为您需要增加直接缓冲内存。参考：https ://groups.google.com/forum/#!topic/druid-user/clGruLMHAgU

在中间管理器配置中，您会发现此选项 druid.indexer.runner.javaOpts 将其设置为更高的值 -XX:MaxDirectMemorySize=4g

参考：druid.io/docs/latest/configuration/index.html
