Is the following akka.conf file valid? - akka

Question

I am using OpenDaylight and trying to replace the default distributed database with Apache Ignite.
I am using the jar obtained by the source code here.
https://github.com/Romeh/akka-persistance-ignite
However, the class IgniteWriteJournal does not seem to load which i have checked by putting some print statements in its constuructor.
Is there any issue with the .conf file?
The following is a portion of the akka.conf file i am using in OpenDaylight.
odl-cluster-data {
akka {
remote {
artery {
enabled = off
canonical.hostname = "10.145.59.38"
canonical.port = 2550
}
netty.tcp {
hostname = "10.145.59.38"
port = 2550
}
# when under load we might trip a false positive on the failure detector
# transport-failure-detector {
# heartbeat-interval = 4 s
# acceptable-heartbeat-pause = 16s
# }
}
cluster {
# Remove ".tcp" when using artery.
seed-nodes = ["akka.tcp://opendaylight-cluster-data#10.145.59.38:2550"]
roles = ["member-1"]
}
extensions = ["akka.persistence.ignite.extension.IgniteExtensionProvider"]
akka.persistence.journal.plugin = "akka.persistence.journal.ignite"
akka.persistence.snapshot-store.plugin = "akka.persistence.snapshot.ignite"
persistence {
# Ignite journal plugin
journal {
ignite {
# Class name of the plugin
class = "akka.persistence.ignite.journal.IgniteWriteJournal"
cache-prefix = "akka-journal"
// Should be based into the the dara grid topology
cache-backups = 1
// if ignite is already started in a separate standalone grid where journal cache is already created
cachesAlreadyCreated = false
}
}
# Ignite snapshot plugin
snapshot {
ignite {
# Class name of the plugin
class = "akka.persistence.ignite.snapshot.IgniteSnapshotStore"
cache-prefix = "akka-snapshot"
// Should be based into the the dara grid topology
cache-backups = 1
// if ignite is already started in a separate standalone grid where snapshot cache is already created
cachesAlreadyCreated = false
}
}
}
}
ignite {
//to start client or server node to connect to Ignite data cluster
isClientNode = false
// for ONLY testing we use localhost
// used for grid cluster connectivity
tcpDiscoveryAddresses = "localhost"
metricsLogFrequency = 0
// thread pools used by Ignite , should based into target machine specs

dataStreamerThreadPoolSize = 1

// to enable or disable durable memory persistance

// used for grid cluster connectivity, change it to suit your configuration

}
}

I assume you modified the configuration/initial/akka.conf. First those sections need to be inside the odl-cluster-data section (can't tell from just your snippet). Also it looks like the following should be:
akka.persistence.journal.plugin = "akka.persistence.journal.ignite"
akka.persistence.snapshot-store.plugin = "akka.persistence.snapshot.ignite"
