FE / 协调节点内存满问题故障排查
防止"FE内存已满"问题,快速恢复,并尽可能找出原因以防止再次发生。
备注
- This information is applicable to FE nodes and Coordinator nodes (shared-data deployments). For readability, we will use "FE" to refer to both types of frontend nodes.
- This article mainly analyzes the situation and solutions of in-heap memory, without covering off-heap memory. If the OOM is caused by off-heap memory issues, consider reducing the JVM XMX configuration or expanding the machine's memory.
