I have set up a neo4j cluster(2.0) with 3 nodes. I am able to see all the
nodes (1 master + 2 slaves) available. Note i haven't created nodes yet.
I want to copy my offline graph data from neo4j 1.8 version to my new
cluster. I have followed the steps from the following link.
http://docs.neo4j.org/chunked/stable/upgrade-guide.html
After the upgrade, slaves are not able to serve any requests. I see
following exception in the logs. Webadmin console shows the slaves are not
available.
org.neo4j.graphdb.TransactionFailureException: Timeout waiting for database
to allow new transactions. Blocking components (1): []
