Hello,
We recently upgraded our product from Flink 1.7.2 to Flink 1.9, and we experience repeated failing jobs with
java.lang.RuntimeException: Could not create file for checking if truncate works. You can disable support for truncate() completely via BucketingSink.setUseTruncate(false).

Reading through https://issues.apache.org/jira/browse/FLINK-13593 , it looks related but this is marked as fixed in 1.9.
Then, the discussion there points to https://issues.apache.org/jira/browse/FLINK-13497 which is marked as unresolved / fixed in 1.10.
Any lights about:
1/ Would you confirm that our stack trace is related with https://issues.apache.org/jira/browse/FLINK-13497 ?
2/ Any ETA for a 1.9.x fixing it?
