在安装过程中,我几乎没有新手问题。让我们说我有3个(让我们命名为A,B,C)不同的Hadoop安装,我只是格式化了B和C.
我尝试了以下内容:
明确使用hadoop distcp hdfs:A
hdfs:B
,由于此错误而无效:
Invalid arguments: Call From Z77H2-A3/127.0.1.1 to local.research.com:8020
failed on connection exception: java.net.ConnectException: Connection
refused; For more details see:

PIG上的结果相同:
main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 2997: Encountered IOException. Call From
local.research.com/127.0.0.1 to 192.168.1.48:9000 failed on connection
exception: java.net.ConnectException: Connection refused;
