spark连接hive数据库-优快云博客

hive在执行查询sql时出现java.lang.IllegalArgumentException: Wrong FS: hdfs://node1:9000/user/hive/warehouse/test1.db/t1, expected: hdfs://cluster1

原因是hadoop由普通集群修改成了高可用集群后没有更改hive设置中warehouse在hdfs上的储存路径
修改hive-site.xml文件内hive.metastore.warehouse.dir的值

将之前的hdfs://k200:9000/user/hive/warehouse 修改为 hdfs://k131/user/hive/warehouse

(这里的hdfs://cluster1是Hadoop配置文件core-site.xml中的fs.defaultFS指定的值)

spark 无法查看 hive 表中原来的内容，只能重新创建新表
