推荐答案

您可以通过添加在/ usr /本地/ sqoop / lib中所有jar文件到HDFS解决这个问题：

You can solve this by adding all jars in /usr/local/sqoop/lib into HDFS :

先在HDFS创建一个目录：

First create a directory in HDFS :

hdfs dfs -mkdir -p /usr/lib/sqoop/lib/

然后把所有libraires到HDFS

Then put all libraires into HDFS

hdfs dfs -put /usr/lib/sqoop/lib/* /usr/lib/sqoop/lib/

然后检查罐子存在于HDFS：

Then check That the jars exists in HDFS :

hdfs dfs -ls /usr/lib/sqoop/lib

使用sqoop Finnaly进口数据：

Finnaly import data using sqoop :

sqoop import --connect jdbc:mysql://localhost/testDB --username root --password password --table student --m 1
