  Administration of the HPE Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Data Fabric Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Data Fabric gateway mediates one-way communication between a source HPE Data Fabric cluster and a destination cluster. You can replicate HPE Data Fabric Database tables (binary and JSON) and HPE Data Fabric Streams streams. HPE Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.

Removing a Service from an Existing Node

Explains how to remove a service from a node.

Procedure

Stop the service you want to remove by using the Control System or the maprcli command-line tool. The following example stops the Fileserver service:
```
maprcli node services -fileserver stop -nodes mapr-node1
```
Purge the service packages with the apt-get, yum, or zypper commands, as suitable for your operating system.
Run the configure.sh script with the -R option.
When you remove the CLDB or ZooKeeper role from a node, run configure.sh -R on all nodes in the cluster.
