  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  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.

- Administering the Data Access Gateway
  The HPE Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Data Fabric cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability

`stream replica resume`

Resumes replication from one stream to another stream Replication can be paused during autosetup and replication phases. When replication resumes, it continues from where it left off.

Permissions Required on the Source Cluster

To run this command, your user ID must have the following permissions:

readAce and writeAce on the volume
lookupdir on directories in the path
adminperm permission on the source stream

NOTE

The mapr user is not treated as a superuser. HPE Data Fabric Streams does not allow the mapr user to run this command unless that user is given the relevant permission or permissions with access-control expressions.

Syntax

CLI	`maprcli stream replica resume -path <stream path> -replica <remote stream path>`
REST	`http[s]://<host>:<port>/rest/stream/replica/resume?path=<path>&replica=<name>`

Parameters

Parameter	Description
`path`	The path and name of the stream that is the source for the replica that you want to resume replicating to.
`replica`	The path and name of the stream replica that you want to resume replicating to.
