当前位置：
hive的元数据用的是mysql，版本是version=1.1.0-cdh5.4.0，一直用的好好的，今天在hive命令行中执行一条select语句，感觉速度很慢，于是强行停止了，结果再也进不去hive命令行了，同时发现NameNode也挂掉了。于是重启NameNode、DataNode和Client，再次通过执行hive还是进不去，报同样的错误：大侠救命啊，如果能解决问题，微信红包送上。以下是报错信息：

没有头绪，请大神指点一下！！！！

没人回答只能靠自己了。。。。。打开hdfs-site.xml里配置的namenode对应的目录
然后查看下面有没有txid 1 没有得话，清空，重新格式化namenode
We expected txid 1, but got txid 686.不一致，可能多次格式的原因
