环境信息：

HDP-3.1.4

已经下载好odjbc8.jar驱动程序放置在/usr/hdp/current/sqoop-client/lib/目录

Sqoop读取Oracle数据库数据导入Hive时，一直卡在INFO hive.HiveImport: Connecting to jdbc:hive2:// 不懂，日志执行到下面这样子就不执行了。

方案一：

在执行sqoop命令的节点新建/etc/hive/conf/beeline-hs2-connection.xml配置文件，内容如下：

beeline.hs2.connection.user

hdfs

beeline.hs2.connection.password

hdfs

由于我们使用hdfs账号进行sqoop导入操作，所以账号和密码都配置成hdfs，比方案二好的地方是，如果hive的配置发生变化，不会被覆盖。

方案二：

参考HiveServer2 Clients配置/etc/hive/3.1.4.0-315/0/beeline-site.xml，修改点如下，原始内容：

beeline.hs2.jdbc.url.container

jdbc:hive2://cdh-m1:2181,cdh-n1:2181,cdh-n2:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2

修改为带用户名密码的

beeline.hs2.jdbc.url.container

jdbc:hive2://cdh-m1:2181,cdh-n1:2181,cdh-n2:2181/;user=hdfs;password=hdfs;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2

之后再执行sqoop import能够正常执行完毕了
