nacos报错Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "I/O dispatcher 245"

根据提供的引用内容，你遇到的问题是nacos报错Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "I/O dispatcher 245"。这个错误通常是由于内存不足导致的。解决这个问题的方法是增加nacos的内存限制。

你可以按照以下步骤来解决这个问题：
1. 找到nacos的启动脚本，通常是一个.sh或.bat文件。
2. 在启动脚本中找到设置JVM参数的地方。
3. 增加-Xms参数来设置JVM的初始堆大小，例如-Xms1024M表示初始堆大小为1024MB。
4. 增加-Xmx参数来设置JVM的最大堆大小，例如-Xmx2048M表示最大堆大小为2048MB。
5. 重启nacos服务。

以下是一个示例的启动脚本，你可以参考它来设置JVM参数：

#!/bin/bash
JAVA_OPTS="-Xms1024M -Xmx2048M"
./nacos-start.sh $JAVA_OPTS

hiveException in thread "main" java.lang.ExceptionInInitializerError

HiveException in the "main" thread with a Java.lang.ExceptionInInitializerError typically indicates a problem occurred during the initialization of a Java application, specifically while setting up or running the Hive (a data warehousing and SQL-like querying tool) within your code. This error is thrown when there's an issue with the Hive Metastore, which is responsible for managing metadata about tables and databases.

Here are some common reasons for such an error:

1. **Dependency issues**: Missing or incorrect dependencies for Hive, Hadoop, or related libraries.
2. **Metastore initialization failure**: A problem with the Hive Metastore service startup, like incorrect configuration or insufficient permissions.
3. **Resource constraints**: Insufficient memory or disk space may lead to the exception.
4. **Incorrect setup**: Misconfigured properties in the Hive-site.xml or other configuration files.
5. **Class initialization errors**: Problems with static initializers in Hive classes that are called early on.

To troubleshoot this issue, you can try the following steps:
- Check the logs for more detailed error messages.
- Ensure all required dependencies are correctly installed and version-compatible.
- Validate your configurations, especially metastore-related ones.
- Verify the application has the necessary permissions to access the resources it needs.
- Run the application in verbose mode to see if any additional information is logged.
