hadoop - 尝试连接时出现Sqoop错误

Question

我正在尝试运行以下Sqoop命令:

sqoop import --connect jdbc:mysql://localhost:3306/sunil_sqoop --table sqoop_emp --username root  --password 225dvrdlr)

但是，我收到此错误:

我该怎么办。

Answer 1

错误:

File does not exist: hdfs://localhost:9000/home/avinash/sqoop-1.4.6.bin__hadoop-2.0.4-alpha/lib/slf4j-api-1.6.1.jar 

您应该将文件slf4j-api-1.6.1.jar复制到HDFS中的目录中:

home/avinash/sqoop-1.4.6.bin__hadoop-2.0.4-alpha/lib/. 

或者，您可以将此jar复制到Oozie sharelib。
