OpDB system requirements
Before you start using the Accumulo parcel, review the prerequisites and system requirements to ensure all requirements are fulfilled.
- Accumulo depends on HDFS and ZooKeeper libraries and configuration information. Therefore, HDFS and ZooKeeper are mandatory services for OpDB.
- Accumulo TabletServers must be collocated with DataNodes.
- Optionally, you can use Accumulo with YARN (MapReduce 2).
