URL: https://github.com/apache/hudi/issues/9244
**Describe the problem you faced**
A few days ago in the production environment, a datanode in the Hadoop
cluster malfunctioned, causing the flink streaming write task( for hudi bucket
mor table) failed. After restarting the Flink task, when we used Spark3.2 or
Presto333 to read data from the table, we found duplicate data under the same
primary key ，yet the duplicate records have the same Hudi system field values
(_hoodie_commit_time, _hoodie_commit_seqno, _hoodie_filename) .
Note: This Flink write task has been running normally for several days.
