尝试解决方案一 发现正如网上所说 使用的数据有一列(last_dt)为null 修正后未恢复正常

尝试解决方案二 修改hdfs文件对于的用户 和 权限 修改后未解决

• hdfs dfs -chown root /user/hive/warehouse/project1.db/demo_ads_apl_nrt
• hdfs dfs -ch’mo’d 777 /uschmoder/hive/warehouse/project1.db/demo_ads_apl_nrt

尝试解决方案三 配置hdfs-site.xml 文件权限 配置后未解决问题

尝试解决方案四 使用 # hive 客户端运行正常

尝试解决方案五 终极大招 重剑无锋 看似最简单的招式就是最牛逼的招式 重新启动hiveServer2服务 后 运行正常

总结 是 hiveServer2服务的某个进程挂了造成的问题
