Discovery

The Stackable Operator for Apache HBase publishes a discovery ConfigMap, which exposes a client configuration bundle that allows access to the Apache HBase cluster.

Example

Given the following HBase cluster:

apiVersion: hbase.stackable.tech/v1alpha1
kind: HbaseCluster
metadata:
  name: {cluster-name} (1)
  namespace: {namespace} (2)
spec:
  clusterConfig:
    hdfsConfigMapName: {hdfs-cluster-name} (3)
    zookeeperConfigMapName: {zookeeper-znode-name} (4)
1 The name of the HBase cluster, which is also the name of the created discovery ConfigMap.
2 The namespace of the discovery ConfigMap.
3 The ConfigMap name to discover the HDFS cluster.
4 The ConfigMap name to discover the ZooKeeper cluster.

The resulting discovery ConfigMap is located at {namespace}/{cluster-name}.

Contents

The ConfigMap data values are formatted as Hadoop XML files which allows simple mounting of that ConfigMap into pods that require access to HBase.

hbase-site.xml

Contains the hbase.zookeeper.quorum property.
