After Upgrading CDH

The following topics describe common actions you must perform after upgrading CDH.

Upgrading Crunch

If you upgrade your CDH cluster, you must modify your project dependencies to match with the new CDH version and rebuild your project. Make sure that all of your dependencies (including Crunch, Hadoop and Spark) use the same CDH version number as your CDH cluster.

Upgrading HBase

Coprocessors and Custom JARs

When upgrading HBase from one major version to another, you must recompile coprocessors and custom JARs after the upgrade.

Never rely on HBase directory layout on disk.

The HBase directory layout is an implementation detail and is subject to change. Do not rely on the directory layout for client or administration functionality. Instead, access HBase using the supported APIs.
