Re: [I] Support SQL Update for CoW when no precombine field is defined [hudi]

nsivabalan commented on issue #16105:
URL: https://github.com/apache/hudi/issues/16105#issuecomment-4795534790

   This appears to be **fixed** on current master. SQL `UPDATE` on a CoW table without `preCombineField` works today:
   
   - `TestUpdateTable.scala` (lines 496-531) creates a CoW table with `primaryKey = 'id'` and no `preCombineField`, then runs `UPDATE` successfully.
   - HUDI-8551 (commit `8f6b1aed3ef7`, "Support no precombine field with EVENT_TIME_ORDERING merge mode") removed NPE paths when the precombine field is missing.
   - `UpdateHoodieTableCommand` contains no validation requiring a precombine field.
   
   If you can still reproduce the original error on the latest master (with table version 8/9), please share a minimal repro and we can re-open. Otherwise this can likely be closed.
   
   _Triaged with Claude Code._
