Neo4j HA

[bigtoch]

Hi,

I have followed the doc on the neo4j site :
http://docs.neo4j.org/chunked/milestone/ha-setup-tutorial.html to
setup the neo4j-HA. I did the coordinators settings and jump to the
neo4j embedded in HA. The server starts very well from my eclipse
console. However when I run the next step using the neo4j console to
continue the rest of the tutorial I got the following message hainfo
unknown command.

Please assist me and educate me on what I am doing wrong.

Arsene,
can't see the command you get anywhere? also, try to set up a local
cluster with https://github.com/neo4j/neo4j-enterprise-local-qa, and
then use similar neo4j.properties files in an embedded GDB config.

Would that work?

Cheers,

Arsene,
remember that you also can examine the cluster status via JMX.

Just start jconsole, and see what JMX info you get, there should be HA
related info under the neo4j namespace?
