HBase to CDP Operational Database Migration Overview

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

CDP Operational Database permits 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, seek advice from Getting Began with Cloudera Knowledge Platform Operational Database (COD).

Now you can migrate your present 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 summary of the HBase migration steps:

Put together for the migration

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

For extra info, in regards to the listed prerequisite duties, see HBase migration conditions.

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 providers, and utilizing the ReplicationSetupTool instrument.

As soon as the replication is ready up, you possibly can migrate your information. To start out the method you first need to disable the replication peer earlier than taking a snapshot. After disabling the replication peer you possibly can 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.

In an effort to confirm that replication was profitable and that the information in your supply and goal clusters are in sync you should utilize the HashTable/CldrSyncTable instrument. 

For extra details about easy methods 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.

*Word: Knowledge replication supported by Cloudera Replication Plug-in will not be a full in-place improve. Full in-place improve is supported solely to CDP Non-public Cloud Base.
