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/ (version 184.108.40.206).
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!!!
