> This seems to be caused by the [HDFS
> IO|https://github.com/apache/beam/tree/master/sdks/java/io/hdfs] components
> guava dependency not being shaded - in contrast to the core components - and
> revealed by the [recent update to
> guava-20.0|https://github.com/apache/beam/commit/0b4b2becb45b9f637ba31f599ebe8be0331bd633]
> and the therefore incorporated api changes made by [overloading
> methods|https://github.com/google/guava/commit/892e323fca32945cdfb25395ca6e346dd0fffa5b#diff-fe7358934fa6eba23c2791eb40cec030]
> Did not check, whether more components are affected to.
