scxwhite opened a new issue #4899:
URL: https://github.com/apache/hudi/issues/4899
**Describe the problem you faced**
I reproduced this problem using the following code(spark local run). In the
following code, I repeatedly update 10000 pieces of data, but if I execute the
following code more than 5 times, the program will report an error.
The problem may occur in clustering. When merging small files, the old
submitted files are
obtained(SparkSizeBasedClusteringPlanStrategy#getFileSlicesEligibleForClustering).
**To Reproduce**
