将数据加载到Druid时出错

Question

我刚接触druid并尝试通过本地文件加载数据。我已经设置了节点和zookeeper实例。我已经在Ubuntu18.04中尝试过，并且工作正常，但是我尝试在lUbuntu中使用它，我看到了下面的错误：

我确实尝试为中层经理增加内存，假设这是导致问题的原因，但这并不起作用。任何帮助都将不胜感激。谢谢！

Answer 1

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

在中间经理配置中，您可以找到此选项，并将其设置为更高的值-XX:MaxDirectMemorySize=4g

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

Answer 2

您应该修改五个进程内存并重新启动
