Subject [jira] [Commented] (FLINK-12172) Flink fails to close pending BucketingSink
Date Tue, 16 Apr 2019 08:56:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-12172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16818789#comment-16818789

Biao Liu commented on FLINK-12172:
----------------------------------

I don't think user should care about pending files. The consumer of BucketingSink should only
read the files without any suffix, and valid-length suffix files if exist. As for the pending/in-progress
files, it seems that there is possibility of leaking. That means consumer would not read
them, moreover nobody would clean them.

> Hello,
> The problem is if you have a BucketingSink, the following case may occur :
> Let's say you have a 2019-04-12–12 bucket created with several files inside which are
pending/finished
>  You create a savepoint and shut down the job
>  After an hour for instance you start the job from the savepoint and a new bucket is
created, 2019-04-16 for instance. 
>  The problem is that the .pending ones from the old buckets seem to never be moved to
finished state if there is a new hourly bucket created.
