Review Comment:
Because this pr make the env.enableCheckpointing updates the env's
configuration. This configuration is utilized as the cluster config when using
LocalExecutor. Consequently, there are places where the toMap method of the
configuration is invoked, such as within the constructor of
ClusterConfigHandler.
However, in Flink the conversion between Duration and String requires that
the maximum value for Duration corresponds to the number of nanoseconds in
Long.MAX_VALUE. Thus, this change was made to adhere to this requirement.
