HBase to CDP Operational Database Migration Overview


This weblog put up supplies an outline of the HBase to CDP Operational Database (COD) migration course of.

CDP Operational Database allows builders to rapidly construct future-proof functions which might be architected to deal with knowledge 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 data 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 may be unsecured or have a unique 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 it’s a must to overview and carry out all the required knowledge migration preparation duties. The required duties rely in your particular cluster setup.

For extra data, 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. Organising the replication
  2. Utilizing a snapshot emigrate knowledge
  3. Optionally, verifying the migration

Replication setup contains 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 may migrate your knowledge. To begin the method you first need to disable the replication peer earlier than taking a snapshot. After disabling the replication peer you may 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 knowledge.

With a purpose to confirm that replication was profitable and that the info in your supply and goal clusters are in sync you need to use 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.

*Be aware: Knowledge replication supported by Cloudera Replication Plug-in just isn’t a full in-place improve. Full in-place improve is supported solely to CDP Non-public Cloud Base.
