I'm just getting started learning MapR-DB (otherwise experienced) and I'm running into a bit of trouble right away that I'm unable to overcome. I'm working on the Docker image.
Working through the DEV330 lab guide, I'm trying to load the sample data for Lesson 1. After
mapr@maprdemo:~$ wget http://course-files.mapr.com/DEV3300-R1/Lesson1.zip
mapr@maprdemo:~$ unzip -o Lesson1.zip
(Works fine, obviously, and yes I checked the file contents) I then try
mapr@maprdemo:~$ mapr importJSON -src /tmp/artists/*.* -dst /apps/artists -bulkload true
Which fails, only outputting the following:
PARSE ARGS: /tmp/artists/00034ede-a1f1-4219-be39-02f36853373e.json
Usage: importJSON [options] -src <Input text file/directory path> -dst <MapR-DB Destination table path>
[-idfield <Name of ID field in JSON Data>]
[-bulkload <true|false>, default is false]
[-mapreduce <true|false>, default is true]
(Can not use bulkload mode with mapreduce = false)
(If no ID field is specified, an ID field is expected to be present in the JSON Record)
This seems to imply that mapr cannot parse my command completely, but I can't find anything at all on why this would be happening or how to improve it. I'm completely stuck. Can anyone help? This makes no sense at all to me. I've tried everything I can think of to try to make it work, only ever getting the same result.
