> Configure FileSystems only once
> -------------------------------
>
> Key: FLINK-7643
> URL: https://issues.apache.org/jira/browse/FLINK-7643
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.4.0
> Reporter: Ufuk Celebi
> Assignee: Stephan Ewen
>
> 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.
