How to open incoming port 50070 in firewall (google compute engine)

[Naveen Subramani]

I have my Single node Hadoop installed on Google Compute Engine instance and i want to open port 50070 on that machine to access the hadoop dashboard for my desktop machine . i configured in the firewall rule to allow tcp:50070 in compute engine networks. but still i am unable to access my port outside the network (ie . via internet). I tried nmap for the public ip of my GCE instance  and it got as port 50070 filtered .but when i try this from an another vm which was launched on the same GCE network i am able to get nmap -p 50070 xxx.xxx.xxx.xxx shows as poet 50070 open ... How to open port 50070 to the external network.

Note: i am using debian 7.5 image 

i created my firewall using this command  

gcutil --project=<myproject id> addfirewall --network=mynetwork hdfs-namenode --description="HDFS NameNode Web console" --allowed="tcp:50070"

I think you need to add target tags (--target_tags) and make sure the instance(s) are also tagged with the same tag.

That's the only way to apply a rule to instances.

Hi Krinesh,

Thank you for bumping this case.

If you are having issues with your instance firewall rules, please use GCP support options in our support Hub. [1] 

There is also a related thread in Stackoverflow by the thread-owner, where you can investigate further. [2]

You can also look into how are firewall rules work here [3] 

This forum is dedicated to discussions on general Google Compute Engine infrastructural issues  and product improvement ideas and the forums above are a better place

to troubleshoot individual instances and issues with your specific environment.
