環境信息：

HDP-3.1.4

已經下載好odjbc8.jar驅動程序放置在/usr/hdp/current/sqoop-client/lib/目錄

Sqoop讀取Oracle數據庫數據導入Hive時，一直卡在INFO hive.HiveImport: Connecting to jdbc:hive2:// 不懂，日志執行到下面這樣子就不執行了。

方案一：

在執行sqoop命令的節點新建/etc/hive/conf/beeline-hs2-connection.xml配置文件，內容如下：

beeline.hs2.connection.user

hdfs

beeline.hs2.connection.password

hdfs

由于我們使用hdfs賬號進行sqoop導入操作，所以賬號和密碼都配置成hdfs，比方案二好的地方是，如果hive的配置發生變化，不會被覆蓋。

方案二：

參考HiveServer2 Clients配置/etc/hive/3.1.4.0-315/0/beeline-site.xml，修改點如下，原始內容：

beeline.hs2.jdbc.url.container

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

修改為帶用戶名密碼的

beeline.hs2.jdbc.url.container

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

之后再執行sqoop import能夠正常執行完畢了

總結
