> HadoopFileSystem always reloads GlobalConfiguration, which potentially leads to a lot
of noise in the logs, because this happens on each checkpoint.
> Instead, file systems should be configured once upon process startup, when the configuration
is loaded.
> This will also increase efficiency of checkpoints, as it avoids redundant parsing for
each data chunk.
