Subject [jira] [Comment Edited] (BEAM-17) Add support for new Beam Source API
Date Wed, 21 Sep 2016 11:44:20 GMT

Since the SDK has moved to the Apache Incubator, it now provides a Runner API and "matching"
InputFormats doesn't seem like the "Beam way".
Instead, it seems that a solution in the form of creating an RDD backed by BoundedSource makes
more sense.

TransformTranslator. This can be done by creating a new SourceInputFormat class that translates
from a DF Source to a Hadoop InputFormat. The two concepts are pretty-well aligned since they
both have the concept of splits and readers.
> Note that when there's a native HadoopSource in DF, it will need special-casing in the
code for Read since we'll be able to use the underlying InputFormat directly.
> This could be tested using XmlSource from the SDK.
