table replica remove

De-registers the specified HPE Data Fabric Database binary or JSON table as a replica.

Permissions Required

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

  • readAce and writeAce on both the source volume and the target volume
  • lookupdir on directories in the paths of both tables
  • replperm permissions on the source table
NOTE
The mapr user is not treated as a superuser. HPE Data Fabric Database does not allow the mapr user to run this command unless that user is given the relevant permission or permissions with access-control expressions.

After running this command, the specified table or index is no longer a replica of the source table and will no longer receive updates from the source table.

In addition, run the table upstream remove command to remove the association between the source table and the replica table.

Parameters

Parameter Description
path

The path to the source table that is being replicated.

  • For a path on the local cluster, start the path at the volume mount point. For example, for a table named testsrc under a volume with a mount point at /volume1, specify the following path: /volume1/testsrc
  • For a path on a remote cluster, you must also specify the cluster name in the path. For example, for a table named customersrc under volume1 in the sanfrancisco cluster, specify the following path:/mapr/sanfrancisco/volume1/customersrc
replica

The path to the replica.

  • For a table on the local cluster, start the path at the volume mount point. For example, for a table named testdst under a volume with a mount point at /volume1, specify the following path: /volume1/testdst
  • For a table on another cluster, you must also specify the cluster name in the path. For example, for a table named customerdst under volume1 in the sanfrancisco cluster, specify the following path: /mapr/sanfrancisco/volume1/customerdst

De-registers table custAdst as a replica of table custAsrc:
