Labels: pull-request-available (was: )
> NPE when notifyNewBufferSize
> ----------------------------
>
> Key: FLINK-24468
> URL: https://issues.apache.org/jira/browse/FLINK-24468
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.14.0
> Reporter: Anton Kalashnikov
> Assignee: Anton Kalashnikov
> Priority: Major
> Labels: pull-request-available
>
> In my opinion, we have two problem there:
> # The exception itself(see below)
> # Ignoring the exception and stopping rescheduling of the calculation of the
> buffer size.
> Of course, we need to fix this NPE and we need to think what we want to do if
> the buffer debloat fails with error.
