HBase to CDP Operational Database Migration Overview

This weblog submit gives an outline of the HBase to CDP Operational Database (COD) migration course of.

CDP Operational Database allows builders to shortly construct future-proof purposes which are architected to deal with information evolution. It helps builders automate and simplify database administration with capabilities like auto-scale and is absolutely built-in with Cloudera Knowledge Platform (CDP). For extra info and get began with COD, consult with Getting Began with Cloudera Knowledge Platform Operational Database (COD).

Now you can migrate your current HBase workloads to COD* with the Cloudera Replication plugin. Cloudera Replication plugin permits communication between the kerberized cluster in COD and the supply cluster which could be unsecured or have a distinct Kerberos realm.

The next is an outline of the HBase migration steps:

Put together for the migration

Earlier than you begin the migration course of you must overview and carry out all the mandatory information migration preparation duties. The mandatory duties rely in your particular cluster setup.

For extra info, concerning the listed prerequisite duties, see HBase migration stipulations.

Migrate your HBase to CDP Operational Database (COD)

The HBase to COD migration course of has three phases:

1. Establishing the replication
2. Utilizing a snapshot emigrate information
3. Optionally, verifying the migration

Replication setup consists of configuring the beforehand talked about Cloudera Replication Plugin, configuring the HBase and HDFS companies, and utilizing the ReplicationSetupTool instrument.

As soon as the replication is about up, you’ll be able to migrate your information. To start out the method you first must disable the replication peer earlier than taking a snapshot. After disabling the replication peer you’ll be able to create, export, confirm and restore a snapshot. After the snapshot is restored on the goal cluster, allow the replication peer on the supply cluster to start replicating information.

With the intention to confirm that replication was profitable and that the information in your supply and goal clusters are in sync you need to use the HashTable/CldrSyncTable instrument. 

For extra details about learn how to migrate your HBase from CDH or HDP to CDP Operational Database (COD), see the HBase migration from CDH/HDP to COD CDP Public Cloud migration information.

*Observe: Knowledge replication supported by Cloudera Replication Plug-in shouldn’t be a full in-place improve. Full in-place improve is supported solely to CDP Non-public Cloud Base.
