Hi All,

I have installed elasticsearch 5.6.4 on windows and have installed JDBC plugin from [http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/](http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/) (version 2.3.4.1).

When I tried to build an index from my sql server DB using this, I got NoNodeAvailableException in the jdbc logs.

When I checked elastic logs, it said "Received message from unsupported version: [2.0.0] minimal compatible version is [5.0.0].

Can someone pls guide me what version is this error message about and how do i upgrade it to [5.0.0]

Thanks in advance!!!

Looking at the matrix that @jprante wrote at [https://github.com/jprante/elasticsearch-jdbc](https://github.com/jprante/elasticsearch-jdbc) and some issues like

It seems like the project is not compatible with 5.x.

There is a 5.0 branch though: [https://github.com/jprante/elasticsearch-jdbc/tree/5.0](https://github.com/jprante/elasticsearch-jdbc/tree/5.0)  
Unsure what is its state.
