# Example This document will explain how to load maps in hazelcast and view them on screen ## 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 `/hazelcast-cluster-startup-1.0.0` folder to classpath: `CLASSPATH="/hazelcast-cluster-startup-1.0.0.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: `Apr 20, 2018 3:04:29 PM com.hazelcast.core.LifecycleService INFO: HazelcastClient[hz.client_0_dev][3.4.6] is STARTING Apr 20, 2018 3:04:29 PM com.hazelcast.core.LifecycleService INFO: HazelcastClient[hz.client_0_dev][3.4.6] is STARTED Apr 20, 2018 3:04:29 PM com.hazelcast.core.LifecycleService INFO: HazelcastClient[hz.client_0_dev][3.4.6] is CLIENT_CONNECTED Apr 20, 2018 3:04:29 PM com.hazelcast.client.spi.impl.ClusterListenerThread INFO: Members [1] { Member [localhost]:5701 }` ## Steps to check value in map - Open browser and enter url `http::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.
