  • 遇到问题

    (1)在使用eclipse远程调用hadoop时,抛出的异常,eclipse默认使用的是8020端口,而我的nameNode使用的9000,所以我将nameNode的端口设置为8020,问题解决

    java.net.ConnectException: Call From LAPTOP-FD4J94H3/192.168.177.111 to hadoop-node1.com:8020 failed on connection exception: java.net.ConnectException: Connection refused: no further information; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
