[jira] [Created] (HUDI-6047) Clustering operation on consistent hashing resulting in duplicate data

Rohan created HUDI-6047:
---------------------------

             Summary: Clustering operation on consistent hashing resulting in duplicate data
                 Key: HUDI-6047
                 URL: https://issues.apache.org/jira/browse/HUDI-6047
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Rohan


Hudi chooses consistent hashing bucket metadata file on the basis of r{*}eplace commit logged on hudi active timeline{*}. but {*}once hudi archives timeline{*}, it falls back to *default consistent hashing bucket metadata* that is  , which result in writing duplicate records in the table *00000000000000.hashing_meta.* 

above behaviour results in duplicate data in the hudi table.

 

Check the loadMetadata function of consistent hashing index implementation.

let me know if anything else is needed.
