Cloudera Migration Assistant server deployment

You can deploy the Cloudera Migration Assistant server (cma-server) to any of your source cluster nodes, or in the case of local or docker mode, to an external node that has visibility to the cluster. It requires 1.5 GB of extra memory, and unless you are in parcel deployment mode, you can install Cloudera Migration Assistant with or without internet connection. You can choose between deploying the Cloudera Migration Assistant server locally, using Docker or with parcel.

Dependencies

The following components must be installed on the cma-server host:

Python 3.8.12 or higher version
Docker deployment requires docker 20+ or higher versions
Local and parcel feployment requires JDK11 (with JAVA_HOME set)

In case you do not have JDK11 installed on you cluster, you can download it using the following commands:

wget https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz -C /usr/java/
ln -s /usr/java/jdk-11 /usr/java/jdk-11.0.2/

You can skip specifying Java Home if it is located on any of the following default paths:

/usr/lib/jvm/java-11
/usr/java/jdk-11
/usr/lib/jvm/jdk-11
/usr/lib64/jvm/jdk-11
/usr/lib/jvm/zulu-11
