Getting HTTP 502 bad gateway error!

Bhargav Shir 0 Reputation points

Hello all,

I am suddenly getting an HTTP 502 and DRIVER_LIBRARY_INSTALLATION_FAILURE error during the Python library installation when the cluster gets initialized. I have around 10 Python packages out of which 2-3, packages always failed to install and packages. The confusing part is, these erroneous packages get changed each time I restart my cluster. Here are the primary details:

Databricks Runtime Version: 12.2 LTS ML

Node Type: Standard F4


Can anyone please guide me on this? Thanks in advance!

    @Bhargav Shir - Thanks for the question and using MS Q&A platform.

    The HTTP 502 bad gateway error you are seeing during Python library installation in Azure Databricks can be caused by a variety of issues. Here are some steps you can take to diagnose and resolve the issue:

    Check the cluster logs: Check the cluster logs to see if there are any error messages or warnings that can help you identify the issue. You can access the logs in the Azure portal by going to your Databricks workspace and selecting "Clusters" under the "Compute" section => Select cluster and view driver logs.

    Check the Python packages: Check the Python packages you are trying to install to make sure that they are compatible with the Databricks Runtime Version you are using. You can check the package compatibility in the Databricks documentation or contact the package vendor for more information.

    Check the network connectivity: Check the network connectivity between your Databricks workspace and the package repository to make sure that there are no network issues. You can use tools like Telnet or Ping to test network connectivity.

    Check the cluster configuration: Check the cluster configuration to make sure that it has the necessary resources and dependencies to install the Python packages. For example, you may need to increase the cluster size or install additional dependencies.

    Contact Databricks support: If none of the above steps resolve the issue, you may need to open a support ticket for further assistance. They can help you diagnose and resolve the issue from their end.

    In summary, the HTTP 502 bad gateway error you are seeing during Python library installation in Azure Databricks can be caused by a variety of issues. You can check the cluster logs, Python packages, network connectivity, cluster configuration, or contact Databricks support to diagnose and resolve the issue.
