-----------------------------------
hi, [~aljoscha] Thank you for your reply！
There are the following points:
1.What I described above is that there will be such a situation when there is
no failure in this job.
2.This happens when a job has a failure(because one of the taskmanager nodes
downtime) and recovery. Fault tolerance of a node in distributed computing is
necessary.Because this is a problem in this case.
3.When recovery, the previous in-progress and pending files are not
cleared，this causes the downstream processor to read excess dirty data.
5.I think we should first place data in computing nodes' local files, then
upload them to the distributed file system after the local file is written
completely, for example, S3, HDFS.
We are blocked of the problem at the moment. and because of this problem, we
can't use this job.
