这里要说一下网上说的都是如何切换hdfs namenone其实是治标不治本
而且没有办法完成hdfs自动切换,尤其是hive。根本的解决办法是将所有指向原hdfs地址的ip修改为HA后的新hdfs组ID才可以。
解决:
1.我用的hive在读取元数据时出错,修改hive元数据SDS表中的LOCATION字段,将原有指向修改为dfs.nameservices的值
例子:
dfs.nameservices=NameNode
原地址
hdfs://NameNode01:8020/tmp
修改为
hdfs://NameNode/tmp
2.hive的catlog地址同上,在hive元数据ctlgs表中
3.hive的database地址同上,在hive元数据dbs表中
