> I upgrade the standalone cluster(3 machines) from flink1.9 to flink1.10.0
> latest. My job running normally in flink1.9 for about half a year, while I
> get some job failed due to null pointer exception when checkpoing in
> flink1.10.0.
> Below is the exception log:
> !image-2020-04-30-18-55-53-779.png!
> I have checked the StreamTask(882), and is shown below. I think the only case
> is that checkpointMetaData is null that can lead to a null pointer exception.

> I do not know why, is there anyone can help me? The problem only occurs in
> Flink1.10.0 for now, it works well in flink1.9. I give the some conf
> info(some different to the default) also in below, guessing that maybe it is
> an error for configuration mistake.
