Neo4j 2.2.2 server not starting after db creation via java code
I am new to Neo4j. I am trying to run some Java application using Neo4j 2.2.2 along with Spring Data. I am using spring-data-neo4j (2.2.2.RELEASE) to connect Neo4j DB. I have successfully completed all CRUD operations using repositories in Spring Data. But I cannot open and view this DB in the Neo4J UI tool. When I try to start the Neo4J server from the console, I get the following error.
emuser1@em02-desktop:~/Installations/neo4j-community-2.2.2/bin$ ./neo4j start
WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
Starting Neo4j Server...WARNING: not changing user
process [14509]... waiting for server to be ready.. Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.
I checked the message.log file in my DB repository. Below are the exceptions.

Can anyone help me. Is there something I am doing wrong?
Thanks in advance.
Note. I have the same question as here . But there is no satisfactory answer.

You have version confusion. Spring Data Neo4j 2.2.2 works with Neo4j 1.9 or so. SDN 3.0 with Neo4j 2.0 and SDN 3.3.1 only (to be released) with Neo4j 2.2.2. SDN 3.3.0 works with Neo4j 2.1.x
This is why it asks you for a config setting allow_store_upgrade=true
in conf/neo4j.properties
.
But I recommend upgrading your SDN project to SDN 3.3.0, then reimport your data and still upgrade from Neo4j 2.1 to 2.2, but at least you will have schema labels and indices.
