Support for Line & Polygon? about geoprocessing-tools-for-hadoop

JSON To Features is expected to work with all of Point, Line, and Polygon.
In fact, Vehicle Trip Discovery with GIS Tools for Hadoop shows an example with Polygon.

Thanks Randall, I will check that link.
The funny thing is:
I export a Poly-FC with the tool "Feature to JSON" (attached in the post above).
So I would expect that this JSON-file should be a valid input for the tool "JSON to Features". But it throws an error ("sequence size must match size of the row").

[randallwhitman]

That does not sound right.

hmmm... let me see

Here we go.
The provided file contains fields named SHAPE_Length, SHAPE_Area while the code checks for Shape_Length and Shape_Area (which is the way it's spelled in FGDB). It's easy to fix.
I wonder, where the alternative spelling is coming from?

[StefanJaq]

Thanks for the Research.
The fGDB and the FC were created with ArcGIS (ArcCatalog) 10.5 and the fieldnames are written SHAPE_Length, SHAPE_Area.
Now I changed the filednames in the JSON and now it works. Thanks for the hint.

@StefanJaq Thanks, I can see it now. I've installed a quick fix for this issue. Please pull the latest code from the repo & let us know it it works for you!

[StefanJaq]

Sorry, the quick fix doesn't really solve the issue. I still get the same error ("sequence size must match size of the row") when trying to import the JSON.
The output json-file itself seems now right. SHAPE_Length and SHAPE_Area are spelled in the same manner in the whole file.

@azhigimont Any idea why it didn't help?
