JSON import not working

[jmvanel]

I'm using Karma for the first time,
and I'm assuming that it's OK to import a JSON with no model pre-existing.

I tried from the web UI (gihub clone) this JSON URL:
http://data.iledefrance.fr/api/datasets/1.0/search?rows=100
I raised the memory to 3Gb ; but it's real slow, and it takes 100% of both CPU's,
and it ends up in "OutOfMemoryError: GC overhead limit exceeded" anyway.

But the data, after download with wget, is not huge:
% wc data.iledefrance.fr_search_rows_100.json
0 19320 206512 data.iledefrance.fr_search_rows_100.json

Then I retarted, and tried this smaller JSON URL:
http://data.iledefrance.fr/api/datasets/1.0/search?rows=20

Now no CPU used, no special message on the console, and running forever in the browser.

Hi, we are looking at your problem. I was able to load the large file in the development version of Karma on a Mac and Chrome. Did you change the default memory allocation for maven:
export MAVEN_OPTS=-Xmx4096m

The default is very small.

We found the problem. We can load the JSON as a file after we download it, but somehow doing it directly from the service is not working. We'll look into it, but we have a few urgent tasks to complete before we get to this one. Hopefully you can still work by downloading the files first. Not ideal, but a temporary workaround.

Indeed it works from the file.
And not with memory as large as 5Gb.

Also I understood from the doc, although it's not stressed, that one must first import a small file, then m
