   > How could it failed then
   
   For eg, if you choose a given merger class with some logic, and hudi does 
not find the class it will run an other default merger silently.
   
   You end up with a upsert with other logic you wanted initially. What I call 
corrupted table
   
   It should fail if the class is not found. No replace by default silently

avro, if we choose the correct merger for the records type, it should not fail, 
maybe we just need to fix the merger class inference instead of throwing.
