Antoine Pitrou commented on ARROW-6760:
---------------------------------------
Hmm, we should probably give better error messages. [~bkietz]
In this case, though, it seems the "length" field is first a string, then an
integer. Arrow only accepts homogenous JSON, i.e. all objects in the same file
must have the same schema.
