I have released JDBC importer 184.108.40.206 which is compatible to Elasticsearch 2.1.1
There is not much functionality that has changed or added. Detected JSON can now be parsed as lists/maps, thanks to a contribution by Simon J Hewitt.
Please try this new release, all feedback and contributions are welcome. The Elasticsearch community is really great. I will still continue to work on JDBC importer in 2016 on a voluntary basis and I have many plans for improvements.
I wish you a merry christmas and a happy new year 2016!
P.S. if you want to honor me for my work, you can now send me a donation. See the button at https://github.com/jprante/elasticsearch-jdbc Thanks for your support!
