consistent with Flink default filesystem
URL: https://github.com/apache/flink/pull/6887#issuecomment-445095013
This may break [FLINK-6376] for the application probably will not apply for
the HDFS delegation that YARN uses for log aggregation, hence close this PR.

> Project: Flink

> Components: YARN
> Affects Versions: 1.6.1
> Reporter: Paul Lin

> Currently, Flink client uses the raw default Hadoop filesystem to upload
> local files, and this could be problematic when using a non-default
> filesystem for HA or checkpointing in delegation tokens scenarios. The
> jobmanager only has the delegation tokens for the default FS, so it gets
> authentication errors when trying to connect a non-default filesystem.
> So I propose to replace the default FS property in yarn configuration with
> the Flink filesystem property `fs.default-scheme` on the client side
> (AbstractYarnClusterDescriptor), to avoid this problem and also make the
> client behavior more configurable.
