It looks like a constant, i.e., it shouldn't be mutable.
```
private static final List<JobStatus> GLOBALLY_TERMINAL_JOB_STATUS =
Collections.unmodifiableList(
Arrays.stream(JobStatus.values())
.filter(JobStatus::isGloballyTerminalState)
.collect(Collectors.toList()));
```
Using `@BeforeClass` is not idiomatic imo.
> Add SerializableExecutionGraphStore to Dispatcher
> -------------------------------------------------
>
> Key: FLINK-8453
> URL: https://issues.apache.org/jira/browse/FLINK-8453
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination, REST
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Major
> Labels: flip-6
> Fix For: 1.5.0
>
>
> The {{Dispatcher}} should have a {{SerializableExecutionGraphStore}} which it
> can use to store completed jobs. This store can then be used to serve
> historic job requests from the web UI, for example. The default
> implementation should persist the jobs to disk and evict the in memory
> instances once they grow to big in order to avoid memory leaks. Additionally,
> the store should expire elements from disk after a user defined time.
