> 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.
