Syntax

CLI

maprcli table region split

  -fid <fid>

Parameters

Parameter	Description
path	Path to the table. For a path on the local cluster, start the path at the volume mount point. For example, if you want to split regions in a table named `test` under volume1 which has a mount point at /volume1, specify the following path: `/volume1/test` For a path on another cluster, you must also specify the cluster name in the path. For example, if you want to split regions in a table named `customer` under volume1 in the sanfrancisco cluster, specify the following path:`/mapr/sanfrancisco/volume1/customer`
fid	The FID of the region to split. The output of `maprcli` `table region list` lists the FIDs for the table's regions.

Parameter

Description

path

Path to the table.

For a path on the local cluster, start the path at the volume mount point. For example, if you want to split regions in a table named test under volume1 which has a mount point at /volume1, specify the following path: /volume1/test

For a path on another cluster, you must also specify the cluster name in the path. For example, if you want to split regions in a table named customer under volume1 in the sanfrancisco cluster, specify the following path:/mapr/sanfrancisco/volume1/customer

fid The FID of the region to split. The output of maprcli table region list lists the FIDs for the table's regions.

Example

This example splits a region in the table newtable.

CLI

maprcli table region split -path /my.cluster.com/volume1/newtable -fid 2086.32.131296
