【问题描述】:
我对这个世界很陌生。使用 sqoop 运行导出命令时,我收到以下错误“输入路径不存在:hdfs://quickstart.cloudera:8020/home/cloudera/Test5”。我检查了路径/home/cloudera/Test5,并且该文件存在于路径中。从 sqoop 配置的core-site.xml 文件中可以看到 hdfs 路径的详细信息,当我通过文件浏览器对其进行测试时,只需打开 IE 并输入hdfs://quickstart.cloudera:8020/home/cloudera/Test5,就会出现“无法连接”的消息。我不知道该属性的正确参数值。请帮我解决这个问题。
请在下面找到属性文件参数和错误详细信息。
参数文件
<name>fs.defaultFS</name>
<value>hdfs://quickstart.cloudera:8020</value>
错误
[cloudera@quickstart hadoop-conf]$ sqoop export --connect jdbc:sqlserver://10.34.83.177:54815 --username hadoop --password xxxxxx --table hadoop_sanjeeb3 --export-dir /home/cloudera/Test5 -mapreduce-job-name sqoop_export_job -m 1
