Hadoop is run under a Linux system, but when we access Hadoop HDFs remotely under Windows Eclipse, it is not possible to access each other if the two address is not in the same network segment.Windows tests can be remotely connected, with only a DOS ping.In order to unify the network segment, the virtual machine is bound to be set to the Web address:1.root accoun

Modify virtual local address in Hadoop Linux
Hadoop runs in Linux, but when we remotely access Hadoop HDFS in Eclipse in Windows, if the two sub-addresses are not in the same CIDR Block, they cannot access each other.
In Windows, you only need to ping Dos to test whether remote connection is available.
To unify the network segment, you must set the network address
