HDP uses multiple ports for communication with clients and between service components. For example, the Hive Metastore port represents the port that the metastore database can use to connect and communicate. To enable HDP communication, open the specific ports that HDP uses.
To open specific ports, you can set the access rules in Windows. For example, the following command opens up port 80 in the active Windows Firewall:
netsh advfirewall firewall add rule name=AllowRPCCommunication dir=in action=allow protocol=TCP localport=80
The following command will open up ports 49152-65535 in the active Windows Firewall:
netsh advfirewall firewall add rule name=AllowRPCCommunication dir=in action=allow protocol=TCP localport=49152-65535
The following tables specify which ports must be opened for specific ecosystem components to communicate with each other. Open the appropriate ports before you install HDP.
