Introduction

...

Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs.

...

• Provision a Hadoop Cluster
• Manage a Hadoop Cluster
• Monitor a Hadoop Cluster

Ambari is officially confirmed to work on X86_64 platform with JDK7 on Ubuntu 12/14, CentOS 5/6, SuSE 11, while version for JDK8/Ubuntu16 is still in development.

...

• Node.js dependencies: Ambari uses old version of node.js (v0.10.44) while AArch64 support only comes to v4.x and later.
• Phantomjs dependencies: Ambari uses phantomjs 1.9.8, while AArch64 support only comes to v2.1.0 and later.
• Jars dependencies: some Java projects which referenced by Ambari have no AArch64 support. 

Build

Sources

• Upstream: https://github.com/apache/ambari.git
• Release-2.2.0 is used in this Wiki

Setup Environment

• Ubuntu 16.04 64bit for AArch64, or CentOS7 64bit for AArch64
• Oracle JDK 1.8.0_111-b14

Pre-Requisites

Dependencies

Build Steps

Install Pre-requisities

For Ubuntu:

sudo apt install python python-dev rpm yum build-essential libfreetype6 libfreetype6-dev fontconfig fontconfig-config libfontconfig1-dev libssl-dev openssl findbugs -y

...

sudo yum groupinstall "Development Tools"
sudo yum install python python-devel openssl-devel openssl openssl-libs freetype freetype-devel fontconfig-devel fontconfig gcc gcc-c++ make build autoconf automake cppunit-devel cmake bzip2 rpm-build

Setup maven

The maven comes along with Ubuntu 16.04 is v3.3.9. Ambari requires maven to be 3.0.5. To build v3.0.5, do as:

...

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2016-11-02 01:10:51+0000)
Maven home: /opt/maven
Java version: 1.8.0_101, vendor: Oracle Corporation
Java home: /opt/jdk/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.4.0-45-generic", arch: "aarch64", family: "unix"

Setup python tools

• For python 2.6, download 
  
  

  Code Block
  language bash
  wget http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg#md5=bfa92100bd772d5a213eedd356d64086 sudo sh setuptools-0.6c11-py2.6.egg

  
  

• For python 2.7, download 
  
  

  Code Block
  language bash
  wget https://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg#md5=fe1f997bc722265116870bc7919059ea sudo sh setuptools-0.6c11-py2.7.egg

  
  

Setup nodejs/npm

Nodejs and npm come along with Ubuntu 16.04 are: nodejs@v4.2.6, npm@3.5.2.

...

As long as they are installed, pom.xml in ambari-admin needs to be changed to reflect these versions. The target nodejs/npm version are defined in "configuration" field of "frontend-maven-plugin".

Build PhantomJS

AArch64 is not supported in phantomjs v1.9.8. Attached patch needs to be applied.

...

ent-user@ambari-dk:~$ phantomjs --version
1.9.8

Replace frontend-maven-plugin

Ambari uses fronend-maven-plugin@v0.0.16, which doesn't support AArch64. Do following to rebuild this plugin for AArch64.

git clone https://github.com/eirslett/frontend-maven-plugin.git
cd frontend-maven-plugin
git checkout -b 0.0.16 frontend-plugins-0.0.16
git apply frontend-maven.patch
mvn clean -DskipTests install

Replace leveldbjni

levedbjni is used in Ambari-metrics. It only provides x86/x86_64 version in maven repo. So AArch64 version of leveldbjni needs to be built and installed. Sometimes one leveldbjni test may fail, just ignore the failure.

wget http://pkgs.fedoraproject.org/repo/pkgs/snappy/snappy-1.0.5.tar.gz/4c0af044e654f5983f4acbf00d1ac236/snappy-1.0.5.tar.gz
tar -xf snappy-1.0.5.tar.gz
cd snappy-1.0.5
./configure --disable-shared --with-pic --host aarch64-unknown-linux --build aarch64-unknown-linux
make -j4
cd ..
git clone git://github.com/chirino/leveldb.git
git clone git://github.com/fusesource/leveldbjni.git
export SNAPPY_HOME=`cd snappy-1.0.5; pwd`
export LEVELDB_HOME=`cd leveldb; pwd`
export LEVELDBJNI_HOME=`cd leveldbjni; pwd`
cd leveldb
export LIBRARY_PATH=${SNAPPY_HOME}
export C_INCLUDE_PATH=${LIBRARY_PATH}
export CPLUS_INCLUDE_PATH=${LIBRARY_PATH}
git apply ../leveldbjni/leveldb.patch
wget https://raw.githubusercontent.com/google/leveldb/master/port/atomic_pointer.h -O port/atomic_pointer.h
make libleveldb.a
cd ${LEVELDBJNI_HOME}
git checkout -b 1.8 leveldbjni-1.8
mvn clean install -P all -P linux64 -DskipTests=true

Build Ambari

To build Ambari, a certain version number should be provided. This version number IS 5-DIGITS, not "4-digits" mentioned on Ambari's Wiki Page. The last digit may vary but the first 3 digits should be same as Ambari source version. In our case this is 2.2.0. Patch is provided to make Ambari built on AArch64. 

...

• RPM will be created under  AMBARI_DIR/ambari-metrics/ambari-metrics-timelineservice/target/rpm/ambari-metrics-collector/RPMS/noarch.
