-----------------------------
Fix Version/s: 0.14.0
> 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
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.14.0
>
>
> Hudi chooses consistent hashing committed 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 *00000000000000.hashing_meta* , which result in writing
> duplicate records in the table *.*
> above behaviour results in duplicate data in the hudi table and *failing in
> subsequent clustering operation as there is inconsistency between file groups
> on storage vs file groups in metadata files*
>
> Check the loadMetadata function of consistent hashing index implementation.
