    Description

      1. Create a mongo db and 5 collections
      2. Create kafka topics with 32 partitions on 5 mongo collections
      3. Load 20M items in each mongo collection
      4. Deploy a 2 node 16C, 64G colunar cluster.
      5. Create 20 cbas kafka collections. Ingestion completed.
      6. Create another 20 cbas kafka collections and start the scaling operations from 2 -> 4 -> 8 -> 4
      7. Last scaling operation failed and CP tried to add back the 4 to be ejected nodes back into the cluster before reattempting the scaling operation and that is hug since 12 hours.

      Since then none of the queries are being accepted by the service anymore.
