hive在E-MapReduce集群的实践（一）hive异常排查入门 hive是hadoop集群最常用的数据分析工具，只要运行sql就可以分析海量数据。初学者在使用hive时，经常会遇到各种问题，不知道该怎么解决。 本文是hive实践系列的第一篇，以E-MapReduce集群环境为例，介绍常见的hive执行异常，定位和解决方法，以及hive日志查看方法。
查看已经运行完成的MapReduce作业记录，比如用了多少个Map、用了多少个Reduce、作业提交时间、作业启动时间、作业完成时间等信息。
最近在用flume和sqoop来做非关系数据(日志)和关系数据(MYSQL)迁移到hdfs的工作，简单记录下使用过程，以此总结 一 flume的使用 使用flume把web的log日志数据导入到hdfs上 1 在 elephant 节点上 先安装...
