Control Plane Issues
Incident Report for Cloudera

On Oct 5th, 2023 we had reports from customers that Cloudera Manager instances in their environments were reporting UNREACHABLE status for both Datalake’s and Datahub’s. Upon further investigation, it was identified that two independent production changes were attributed to the issue. 

  1. A new software release for connectivity between Control Plane and Workload; which hit an edge case during certain operations. This was addressed by rolling back to the previous software version. 
  2. The second independent production change was related to a decrease in resources allocated to one of our internal systems; responsible for storing key secrets. This was addressed by reverting to the previous configurations. 

These issues did not manifest in our lower environments, where the changes were tested prior to rolling out to Production. As a mitigation action, our teams are working on adding monitoring and alerting around these corner cases and will introduce additional checks and balances before any resource changes are implemented in our production system.
