It is possible, to connect my Hadoop cluster to multiple Google Cloud Projects at once ?
I can easly use any Google Storage bucket in single Google Project via Google Cloud Storage Connector as explained in this thread Migrating 50TB data from local Hadoop cluster to Google Cloud Storage. But i can't find any documentation or example how to connect to two or more Google Cloud Project from single map-reduce job. Do You have any suggestion/trick ?
Thanks a lot.
Indeed, it is possible to connect your cluster to buckets from multiple different projects at once. Ultimately, if you're using the instructions for using a service-account keyfile, the GCS requests are performed on behalf of that service-account, which can be treated more-or-less like any other user. You can either add the service account email [email protected] to all the different cloud projects owning buckets you want to process, using the permissions section of cloud.google.com/console and simply adding that email address like any other member, or you can set GCS-level access to add that service-account like any other user.
