Question

我正在尝试使用sqoop将mySQL数据导入HDFS。

我的环境是：
Ubuntu 16.04
Hadoop 2.6.0-cdh5.16.1
Sqoop 1.4.7

执行时
sqoop import --connect jdbc:mysql://localhost/crawl_data_stats --username root --password password --table auth_group

我收到以下错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/mapreduce/InputFormat

Answer 1

我查看了Sqoop jar files not found，并将hadoop-mapreduce-client-core-2.7.3.jar复制到/usr/lib/sqoop/sqoop-1.4.7.bin__hadoop-2.6.0/，错误得到了已解决
