This release of the Cloudera Data Warehouse (CDW) service on CDP Public Cloud introduces these changes.

Re-activate your Virtural Warehouse to get these hotfixes.
  • TSB-746: Resolves the issue with the DELETE/UPDATE/MERGE operations that can corrupt the Iceberg V2 tables when an operation runs concurrently with Spark compaction. The position delete files no longer point to the old files.
  • TSB-750: CDW activation resulting in inaccessible workload endpoints on AWS has been fixed.

    CDW activation no longer creates two cloudformation stacks instead of one. This might result in all the workloads being inaccessible depending on which cloudformation stack finishes first.

  • TSB-752: Dangling delete issue in Spark rewrite_data_files procedure causes incorrect results for Iceberg V2 tables. The known issue describing this problem has been fixed.
  • IMPALA-12787: Concurrently running UPDATE and DELETE operations can no longer revive deleted rows.
