URL: https://github.com/apache/hudi/pull/12884#issuecomment-2702879316

   **Simplified Design Approach:**
   1. Retain multi-versioned hashing_config(essential for enabling rollback 
capabilities of Bucket Rescale Actions), with corresponding logic implemented 
for version updates, cleanup, and archival
   2. Remove 'hashing_meta' related design
   3. Provide a Spark call command `partitionBucketIndexManager` to do bucket 
rescale works
   
   **Core Requirement:**
   Before Bucket Rescale using `partitionBucketIndexManager`, **all ingestion 
jobs must be stopped** to ensure the consistency between Data and 
hashing_config.
