                 URL: https://issues.apache.org/jira/browse/HUDI-5406

          Issue Type: Bug
            Reporter: Alexey Kudinkin


For ex, running `ITTestHoodieSanity.testRunHoodieJavaAppOnMultiPartitionKeysCOWTable` produces quite a few of the following exceptions: 
{code:java}

We need to troubleshoot why are these occurring.
