]: Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask

这个错误信息表明在处理Hive语句时出现了问题，返回了错误代码2。这可能是由于多种原因引起的，例如语法错误、权限问题、资源不足等。以下是一些可能的解决方案：

1.检查Hive语句的语法是否正确，特别是在使用关键字和函数时。
2.检查用户是否具有执行该语句所需的权限。
3.检查Hive和Hadoop的版本是否兼容。
4.检查集群的资源是否足够，例如内存和CPU。
5.尝试重新启动Hive服务或整个集群。
