Known Issues and Limitations

  • The Installer can install Airflow, but cannot set up MySQL as the backend database for Airflow. The default Airflow database is SQLite.​
  • Apache PySpark has many CVEs and is removed from the default Airflow dependencies. To use the Spark JDBC operator/hook from Apache, install PySpark as follows:
    1. Run <airflow_home>/build/env/bin/activate.
    2. Run pip install pyspark==3.3.3.
    3. Run deactivate.
    4. NOTE
      This process does not affect the HPE Ezmeral Spark provider.
  • If the repair_pip_depends.sh script fails with the following error, you must run the script again:
    subprocess.CalledProcessError: Command 'krb5-config --libs gssapi' returned non-zero exit      status 127.
