> The CheckpointStatsTracker implements the Serializable interface, even though it no longer is serializable as it contains a List<ExecutionJobVertex>.
> This was introduced in 579bc96446d598a2cfe8237b4ebd62d8c9df3483 which reworked the checkpoint stats tracking,
> This does not affect 1.2 or 1.3 in any way (since these objects aren't serialized there), but it blocks the implementation of the HistoryServer.
> The AccessExecution*/ArchivedExecution* classes, which are supposed to be a serializable form of the ExecutionGraph, are thus broken as they also make use of the CheckpointStatsTracker.
> (Note: * = Graph/ExecutionJobVertex/ExecutionVertex/Execution) .
> This wasn't catched in tests since no ExecutionJobVertices were given to the CheckpointStatsTracker in ArchivedExecutionGraphTest#setExecutionGraph.
