Unable to connect to HBASE due to network limitations

On the server, I found the machine that can ping ZK, and other HBASE machines, but I found that it still could not connect to the HBASE database. The 2222 port under Telnet, the hair line could not be connected. After contacting the information department to open the port, I found that it still did not work. I sorted it out. , the port that the master listens to, and the port that the regionserver listens to. It is found that the three ports 16010, 16020, and 16030 need to be opened again.


This is the master listening, 3 ports

tcp 0 0 ::ffff:172.20.15.29:16020:::* LISTEN 6626/java          
tcp 0 0:::16030:::* LISTEN 6626/java          
tcp 0 0::: 16010 :::* LISTEN 6626/java 

this is regionserver listening

tcp 0 0 ::ffff:172.20.15.27:16020 :::* LISTEN 1080/java          
tcp 0 0 :::16030 :::* LISTEN 1080/java

he behavior:
1.0.0:
RPC: hbase.master.port IS NOT respected. Master binds to hbase.regionserver.port
INFO: Master binds to hbase.master.info.port AND hbase.regionserver.info.port.
By default, master will use: 16010, 16020, 16030
