This allows this library to run against various Spark 3.x versions (tested against 3.3.x and 3.5.x using assemblies generated using this branch). Prior to updating the interfaces, I refreshed the dependencies (including migrating from Spark 2.11 to 2.12) and addressed deprecations (excepting
sbt
's changes to how integration tests are defined).useLocal
works in a cluster environment, but I'm unable to read PBFs larger than the includedsample.pbf
(e.g., Geofabrik extracts) from S3 directly: it begins to read the remote object, but the resulting DataFrame contains 0 rows. I suspect that this is due to howparallelpbf
handles Hadoop'sFSDataInputStream
, potentially across multiple threads, but I've been unable to locate the source of the problem.I'd like to share this as-is to accelerate any potential efforts by others while recognizing that there is still work to be done.
Fixes #3.
