Janus Graph HBase and Solr Unknown external index backend: jgex
mserta...@gmail.com
Hi all,
I work with JanusGraph 0.2.0,Hbase 1.2.6 and Solr 7.3.0. I want to run a standalone Janus Graph server with Hbase(storage backend) and Solr (index backend).Then connect with gremlin driver (with Java Client) and user Gremlin Query language to traverse my graph. I locally installed Hbase and Solr. I followed:
https://github.com/JanusGraph/janusgraph/tree/master/janusgraph-examples/example-remotegraph
Updated gremlin-server.yaml with janusgraph-hbase-solr.properties. I successfully started Gremlin server. I created core jgex with
solr create_core -d $JANUSGRAPH_HOME/conf/solr -c jgex
When I run
mvn exec:java -pl :example-remotegraph
command it throws
