I need access to kafka admin utils to do some admin work. Exposing javaInit method makes it much easier to extend functionality.
const javaInit = require('kafka-java-bridge').javaInit;
const java = javaInit.getJavaInstance()
Example:-
const adminUtils = java.import("kafka.admin.AdminUtils")
const ZKStringSerializer = java.import("kafka.utils.ZKStringSerializer$")
const ZKUtils = java.import("kafka.utils.ZkUtils")
const ZkClient = java.import("org.I0Itec.zkclient.ZkClient")
const zkClient = new ZkClient(
${kafkaConf.host}:${kafkaConf.port}
, 10 * 1000, 8 * 1000, ZKStringSerializer.MODULE$)const topicProperties = java.newInstanceSync("java.util.Properties")
/**
*/
function createTopic(name, numPartitions, replicationFactor) {
try {
adminUtils.createTopicSync(zkClient, name, numPartitions, replicationFactor,topicProperties)
} catch (ex) {
throw ex
}
}
