[jira] [Created] (HUDI-3343) Metadata Table includes Uncommitted Log Files during Bootstrap

Alexey Kudinkin created HUDI-3343:
-------------------------------------

             Summary: Metadata Table includes Uncommitted Log Files during Bootstrap
                 Key: HUDI-3343
                 URL: https://issues.apache.org/jira/browse/HUDI-3343
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Alexey Kudinkin


While working on a fix for HUDI-3322, discovered a following issue:

If we're bootstrapping the MT during pending Rollback operation (this could happen when previous writer had MT *disabled* when writing the data), since bootstrapping is done _after_ Rollback is executed (with its side-effects already being reflected on FS) bootstrapping would incorrectly include intermediary files created by the Rollback (like log-files being created with Rollback Command Block appended).

 

Filtering of the files is performed here:
