   > hey @ganczarek : looks like there is a bug https://issues.apache.org/jira/browse/HUDI-3346. we will work on the fix. should be straight forward. Atleast in this case, manually deleting the commit meta file just for this instant should be fine. Here is what could have resulted in this.
   > 
   > Just before downgrade, a commit was started, but before going into inflight or before a single marker file could be created, the process crashed. And so there is no marker dir only created for this commit. Downgrade code missed to check for existence in one place (but there are other places where this check is made) and so it failed.
   > 
   > I have created a tracking [ticket](https://issues.apache.org/jira/browse/HUDI-3346) here. We are good to close this.
   
   Sorry, I missed this.  There should be a check for marker directory before trying to delete it, which is missing before.
