Sqoop写入Hive卡在连接Hive的JDBC上不执行

Sqoop访问 启用 HA模式的Hive

找到Hive的安装根目录：$HIVE_HOME/conf
创建一个新的配置文件：beeline-hs2-connection.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property><name>beeline.hs2.connection.user</name><value>hive</value>
</property>
<property><name>beeline.hs2.connection.password</name><value>hive</value>
</property>
</configuration>

beeline.hs2.connection.user：指定Hive访问的用户名
beeline.hs2.connection.password：当前用户名对应的访问密码

重新执行后发现会有新的报错信息：

解决办法：

1-新建一个存储格式为textfile的临时表

create table hive_db.hive_01( id string comment 'Id') 
row format delimited fields terminated by '\001' 
stored as textFile;

2-将数据导入临时表中（Sqoop执行的Import写入到临时表中）
3-通过查询插入的方式将临时表数据导入目标表

insert into hive_db.hive_table select * from hive_db.hive_01
