Accessing GCS with Hadoop client from outside of Cloud - google-cloud-platform

Question

I want to access Google Cloud Storage via Hadoop client. I want to use it on machine outside of Google Cloud.
I followed instructions from here.
I created service account and generated key file. I also created core-site.xml file and downloaded the necessary library.
However, when I am trying to run simple hdfs dfs -ls gs://bucket-name command, all I get is this:
Error getting access token from metadata server at: http://169.254.169.254/computeMetadata/v1/instance/service-accounts/default/token
When I am doing this inside the Google Cloud it works, but trying to connect to GCS from outside, it shows error above.
How to connect to GCS with Hadoop Client in this way? Is it even possible? I have no route to 169.254.169.254 address.
Here is my core-site.xml(I changed the key path and email in this example):
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

could be that the hadoop services haven’t taken the updates made in your core-site.xml file yet, so my suggestion is restart the hadoop’s services,another action that you can take is check the Access control options[1].
If You still having the same issue after having taken the action suggested, please post the complete error message.

Answer 2

The problem is with the fact that I've tried wrong authentication method. Used method assumes that it's running inside google cloud and it's trying to connect to google metadata servers. When running outside of google it doesn't work for obvious reasons.
The answer to this is here: Migrating 50TB data from local Hadoop cluster to Google Cloud Storage with the proper core-site.xml in the selected answer.
Property fs.gs.auth.service.account.keyfile should be used instead of spark.hadoop.google.cloud.auth.service.account.json.keyfile. The only difference is that this property needs p12 key file instead of json.
