Hi wangsan,
What I mean is establishing a connection each time write data into JDBC,
i.e. establish a connection in flush() function. I think this will make
sure the connection is ok. What do you think?

Thanks for the link. Yes your are rights and it works fine. But when I use the

Hi Lasse
As far as I know, if you use post /jars/upload REST API to submit your job,
you can then get /jars to list your user jar just uploaded. More information

Thanks for the reply Till. Resubmitting the job is an option.
I was wondering if there's any way that Flink could be configured to detect
issues like a memory issue and rescale without me submitting the job again.

Hi.
I working on a solution where I want to check if a running job use the
right jar in the right version.
Anyone knows if it is possible through the REST API to find information
about a running job that contains the jarid or something simillary so it is
possible to lookup the original jar?

Hi Hequn,
Establishing a connection for each batch write may also have idle connection
problem, since we are not sure when the connection will be closed. We call
flush() method when a batch is finished or snapshot state, but what if the

Hi Teena,
It seems that a sink can not output data into another sink. Maybe we can
implement a combined user defined sink. In the combined sink, only write to
the next sink if the first write is successful.

That makes sense, what does not make sense is that the pipeline restarted.

Adding to the previous question, is it possible to check if each record in a

the records to the next sink only if the first write is successful. So,
replicating the streams before the write is not an option.

Hi Vishal,
it looks as if the flushing of the checkpoint data to HDFS failed due to
some expired lease on the checkpoint file. Therefore, Flink aborted the
checkpoint `chk-125` and removed it. This is the normal behaviour if Flink
cannot complete a checkpoint. As you can see, afterwards, the check
