hadoop - hive 总是减少0％

我使用 hive 来分析数据
我创建表并将本地文件加载到配置单元
当我在 hive 上运行hiveql
select sum(qlog_test.contlength) from qlog_test where qlog_test.area='HK' limit 10;卡在 map 上100％减少0％

这是 map /缩小作业详细信息

最佳答案

我有这个问题。确保查看 reducer 日志。参考您的屏幕快照，单击化简行中的1，然后跟踪记录所有数据的文件。然后，单击“全部”，然后查看导致问题的原因。我遇到的问题是IP配置错误，因此映射器和 reducer 无法通信。重新启动系统很有帮助。编辑您的问题，以包括化简日志所说的内容，也许我们可以为您提供进一步的帮助。
