我试图将数据从远程服务器加载到hive表中，在那里我一次向hive表发送20个请求，我遇到此错误“ [Cloudera] JDBC连接已关闭。” < / strong>并成功处理了部分请求和其余请求，从而可以将数据成功加载到配置单元表中。
连接字符串
ServerUrl=jdbc:hive2://hhhjkh.ghcprp.com:10000/hjhjhkhjkhj;principal=hive/hhhjkh.ghcprp.com@internal.cvbglobal.com;SSL=1;mapred.job.queue.name=la9;AuthMech=3;user=xxxxxxx;password=xxxxxxx;SocketTimeout=0
错误
