Due to the nature of Apache Mesos and the potential for Riak nodes to come and
go on a regular basis, client applications using a Mesos based cluster must
be kept up to date on the cluster's current state. Instead of requiring this
intelligence to be built into Riak client libraries, a smart proxy application named
Director has been created which can run alongside client applications.
The Director communicates with Zookeeper to keep up to date with Riak cluster changes. The Director in turn will update it's list of balanced Riak connections.
After locating your Director's address in Mesos, the HTTP API can be utilized:
| Name | Method | Path | Description |
|---|---|---|---|
| status | GET | /status |
Display current information about the director |
| configure | PUT | /frameworks/{framework}/clusters/{cluster} |
Changes the framework and cluster names |
| listFrameworks | GET | /frameworks |
Lists the currently known Riak Mesos Framework instances |
| listClusters | GET | /clusters |
Lists the clusters for the configured framework |
| listNodes | GET | /nodes |
Lists the nodes for the configured cluster |
| healthCheck | GET | /health |
