Cloud foundry broker for HBase.
To use hbase-broker, you need to build it from sources configure, deploy, create instance and bind it to your app. Follow steps described below.
Run command for compile and package.:
mvn clean package
Broker automatically bind to an existing kerberos provide service. This will provide default kerberos configuration, for REALM and KDC host. Before deploy check:
- if kerberos service does not exists in your space, you can create it with command:
cf cups kerberos-service -p '{ "kdc": "kdc-host", "kpassword": "kerberos-password", "krealm": "kerberos-realm", "kuser": "kerberos-user" }'
- if kerberos-service exists in your space, you can update it with command:
cf uups kerberos-service -p '{ "kdc": "kdc-host", "kpassword": "kerberos-password", "krealm": "kerberos-realm", "kuser": "kerberos-user" }'
Push broker binary code to cloud foundry (use cf client).:
cf push hbase-broker -p target/hbase-broker-*.jar -m 512M -i 1 --no-start
For strict separation of config from code (twelve-factor principle), configuration must be placed in environment variables.
Broker configuration params list (environment properties):
- obligatory
- USER_PASSWORD - password to interact with service broker
- HADOOP_PROVIDED_ZIP - list of hbase configuration parameters exposed by service (json format, default: {})
- optional :
- BASE_GUID - base id for catalog plan creation (uuid)
- CF_CATALOG_SERVICENAME - service name in cloud foundry catalog (default: hbase)
- CF_CATALOG_SERVICEID - service id in cloud foundry catalog (default: hbase)
- ZK_BRK_SPACE - (default: /broker)
For instance.:
cf se hbase-broker ZKCLUSTER_URL 10.10.9.145:2181,10.10.9.146:2181
HBASE client configuration must be set via HADOOP_PROVIDED_ZIP environment variable. Param hbase.zookeeper.quorum
is required. Description of this process is this same as in HDFS broker case ( https://github.com/trustedanalytics/hdfs-broker/ ).
Use cf client :
cf start hbase-broker
Use cf client :
cf create-service-broker hbase-broker <user> <password> https://hbase-broker.<platform_domain>
cf enable-service-access hbase
cf cs hbase bare hbase-instance
Broker instance can be bind with cf client :
cf bs <app> hbase-instance
or by configuration in app's manifest.yml :
services:
- hbase-instance
To check if broker instance is bound, use cf client :
cf env <app>
and look for :
"hbase": [
{
"credentials": {
"HADOOP_CONFIG_KEY": {
<hbase_configuration_json>
},
"HADOOP_CONFIG_ZIP": {
"description": "This is the encoded zip file of hadoop-configuration",
"encoded_zip": "<base64 of configuration>"
}
"kerberos": {
"kdc": "ip-10-10-9-198.us-west-2.compute.internal",
