我正在使用sqoop尝试将sqlserver表导入配置单元。连接字符串工作正常,但导入失败。下面是输出。如果我尝试导入到hdfs中,也会遇到同样的错误。有人知道问题是什么吗?

[cloudera@ushydgnadipalvx sqoop]$ sqoop import --connect "jdbc:sqlserver://[server];username=[username];password=[password];database=[dbname]" --table [tablename] --hive-import

上面显示的输出错误是由于hadoopjar不在类路径中造成的。设置正确的类路径后尝试导入。下面是一个例子 tcsh 贝壳。

setenv CLASSPATH $HADOOP_HOME/lib/*:$CLASSPATH

问题是我有一个名为“text”的列名,这就是导致错误的原因。我通过重命名我的列来修复它。
