Steps to load sample data in Hazelcast cluster

Below steps can be followed to load sample data in Hazelcast IMDG cluster:

Go to the directory where hazelcast cluster is installed and navigate to bin directory.
Add the map's information in hazelcast.xml.For a sample on how to add map information refer hazelcast.xml present under hazelcast-cluster/src/main/resources.
Write loader class to load data in Hazelcast map. For sample refer HazelcastMapLoader.java present under hazelcast-cluster/src/main/java/com/impetus/hazelcast/example.
Run HazelcastMapLoader.java class to ingest records in testMap using below commands:
- Add hazelcast-cluster-startup-1.0.0.jar and lib present in <path to jar>/hazelcast-cluster-startup-1.0.0 folder to classpath: CLASSPATH="<path to jar>/hazelcast-cluster-startup-1.0.0.jar:<path to jar>/lib/*"
- Add main class: CLASSNAME=com.impetus.hazelcast.example.HazelcastMapLoader
- Call main class: java -classpath $CLASSPATH $CLASSNAME
- This should load sample map in hazelcast cluster.
- You will see following logs as shown below:

Open browser and enter url http:<IP Address>:9000/#/hazelcast
To see the data in map, Go to Maps and then to testMap.
Click on Browse.
Add the key in it and click on Browse button. In testMap the keys are : Key1,Key2...Key999.
To clear the Map record from UI, click on Clear tab. It will not remove the data from Hazelcast, but will only clear the screen.
