背景
hive jdbc 的驱动并不是通用的，链接 hive 需要对应版本的 jdbc 驱动
要不然可能会这样：
1 | The specified database user/password combination is rejected: [ 08S01] Could not open client transport with JDBC Uri: jdbc:hive2://192.168.1.***:10000: Could not establish connection to jdbc:hive2://192.168.1.***:10000: Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{set:hiveconf:hive.server2.thrift.resultset.default.fetch.size=1000, use:database=default}) [ 08S01] Could not establish connection to jdbc:hive2://192.168.1.***:10000: Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{set:hiveconf:hive.server2.thrift.resultset.default.fetch.size=1000, use:database=default}) |
- 以 hive 1.2.1 版本为例
驱动
hive 1.2.1, 下载 standalone jar
https://mvnrepository.com/artifact/org.apache.hive/hive-jdbc/1.2.1hadoop common 2.10.0 （这个版本需要根据具体的 hdfs 版本来确认，选择 2.10.0 也不是不行
https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-common/2.10.0
如果没有 hadoop common 包的话，会这样
1 | Driver class 'org.apache.hadoop.conf.Configuration' not found. |
添加 User Driver
