Dear All,

I'm very new to blazegraph but I changed to blazegraph cause of the
clustering possibilities. I'm poor of having trouble with this. I want
to cluster three nodes, all three become members in the quorum but only
two join them.
I discover this with zooinspector.

The only difference between the three servers is that one of them
doesn't have DNS is that a problem? Maybe on you can help me.


My config file looks like this (the same on every machine):

## Configure basic environment variables.  Obviously, you must use your
own parameters for LOCATORS and ZK_SERVERS.

## This will not override parameters in the environment.


# Name of the federation of services (controls the Apache River GROUPS).


if [ -z "${FEDNAME}" ]; then

        export FEDNAME=tgRDFCluster

fi


# Path for local storage for this federation of services.


if [ -z "${FED_DIR}" ]; then

        export FED_DIR=/home/tomcat-sesame/blazegraphCluster/data

fi


# Name of the replication cluster to which this HAJournalServer will belong.


if [ -z "${LOGICAL_SERVICE_ID}" ]; then

        export LOGICAL_SERVICE_ID=tgHA-1

fi


# Where to find the Apache River service registrars (can also use
multicast).


if [ -z "${LOCATORS}" ]; then

        #Use for a HA1+ configuration

        #export LOCATORS="jini://localhost/"

        #HA3 example

        export
LOCATORS="jini://textgrid-test1.gwdg.de/,jini://textgrid-test1.gwdg.de/,jini://141.5.102.206/"

fi


# Where to find the Apache Zookeeper ensemble.


if [ -z "${ZK_SERVERS}" ] ; then

        #Use for single node configuration

        export ZK_SERVERS="localhost:2181"

        #Use for a multiple ZK configuration

        #export ZK_SERVERS="bigdata15:2081,bigdata16:2081,bigdata17:2081"

fi


#Replication Factor (set to one for HA1) configuration


if [ -z "${REPLICATION_FACTOR}" ] ; then

        #Use for a HA1 configuration

        export REPLICATION_FACTOR=3

        #Use for a HA1+ configuration

        #export REPLICATION_FACTOR=3

fi


#Port for the NanoSparqlServer Jetty


if [ -z "${JETTY_PORT}" ] ; then

        export JETTY_PORT=7070

fi


#Group commit (true|false)


if [ -z "${GROUP_COMMIT}" ] ; then

        export GROUP_COMMIT=true
