Gen Luo commented on FLINK-26322:
---------------------------------
I found issues that may relate to 4. The jira is FLINK-26580 and a PR has been
created.
It seems that the compactor is not properly processing the in-progress files,
but we failed to find it since the test case is using a rolling policy that
will force flush the in-progress file before checkpointing. I changed this
policy and two issues arose, both of which are fixed in the newly created PR.
