No, there is no official yum repository for the Google Cloud BigQuery Python module. You can install it manually using the wheel files as described in my previous answer, or you can use pip or easy_install to install it as part of the Google Cloud SDK.
Here's an example of how to install the Google Cloud SDK and the necessary components using yum:
STEP 1. Add the Google Cloud SDK repository:
sudo tee -a /etc/yum.repos.d/google-cloud-sdk.repo << EOM [google-cloud-sdk] name=Google Cloud SDK baseurl=https://packages.cloud.google.com/yum/repos/cloud-sdk-el7-x86_64 enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg EOM
STEP 2. Install the Google Cloud SDK:
sudo yum install google-cloud-sdk
STEP 3. Install the necessary components for the Google Cloud Client Library for Python:
gcloud components install beta bigquery-client
After completing these steps, you should have a working Google Cloud SDK installation, including the components necessary to run queries in BigQuery using the Google Cloud Client Library for Python.
