------------------------------------
Hi,
The mentions of the Checkpointed interface need to be upgraded. Here is a
relevant section in the docs, which explains the change of interfaces between
1.1 ans 1.2:
https://ci.apache.org/projects/flink/flink-docs-master/dev/migration.html#rescaling-and-new-state-abstractions
I suggest using Ctrl+Shift+F in IntelliJ to find all stale mentions of the
Checkpointed interface.
Btw. you can also check out some old commit in git, if you would like to look
at how things were in 1.1.
I also suggest reading this contributor guide:

> Key: FLINK-8116
> URL: https://issues.apache.org/jira/browse/FLINK-8116
> Project: Flink
> Issue Type: Bug
> Components: DataStream API, Documentation
> Reporter: Gabor Gevay
> Priority: Trivial
> Labels: starter
> Fix For: 1.5.0
>
>
> Between Flink 1.1 and 1.2, the {{Checkpointed}} interface was superseded by
> the {{CheckpointedFunction}} interface.
> However, in {{SourceFunction}} there are two comments still referring to the
> old {{Checkpointed}} interface. (The code examples there also need to be
> modified.)
> Note that the problem also occurs in {{StreamExecutionEnvironment}}, and
> possibly other places as well.
