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.

The challenges for AArch64 porting are:

...

On this collaborate page we try to explain how to build and install the Ambari on CentOS 7.4 and Debian 9.0
 

Build

• Upstream: https://github.com/apache/ambari.git
• Release-2.46.2 1 is used in this Wiki

Setup Environment

• Ubuntu 16Debian 9.04 0 64bit for AArch64, or CentOS7 CentOS-7.4 64bit for AArch64Oracle JDK 1.8.0_111-b14

Pre-Requisites

Dependencies

Build Steps

Install Pre-requisities

For UbuntuDebian 9.0:

sudo apt install git 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 git 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.To setup maven 3.95. Ambari requires maven to be 3.0.5. To build v3.0.5, do as:

wget httpshttp://archivewww-eu.apache.org/dist/maven/maven-3/3.05.53/binaries/apache-maven-3.05.53-bin.tar.gz
tar xvf apache-maven-3.05.53-bin.tar.gz
cd apache-maven-3.05.53/bin
export PATH=$PWD:$PATH

Make sure the version of Maven is 3.05.5 3 when the following command is issued.

...

Apache Maven 3.05.53 (r01de14724cdef164cd33c7c8c2fe155faf9602da3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 20162018-1102-02 0124T19:1049:51+000005Z)
Maven home: /opthome/centos/maven/apache-maven-3.5.3
Java version: 1.8.0_101-release, vendor: Oracle Corporation
Java home: /home/centos/opt/jdkjdk8u/jdk8u-server-release-1804/jre
Default locale: en_USIN, platform encoding: UTF-8
OS name: "linux", version: "4.412.0-45-generic1.1.aarch64", 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 The python 2.6 did't work for me, hence I have just created a softlink of v2.6 for v2.7 python $ sudo ln -s /usr/bin/python2.7 /usr/bin/python2.6

  
  

Setup nodejs/npm

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

For Ubuntu/Debian, nodejs/npm can be installed by:

sudo apt-get install -y nodejs npm
cd /usr/bin && sudo ln -s nodejs node
sudo npm install -g brunch@1.7.10

Note that if you are using Debian 9 stretch then please follow the below steps https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions 
sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs
cd /usr/bin && sudo ln -s nodejs node
sudo npm install -g brunch@1.7.10

...

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

The following steps explain about AArch64 is not supported in phantomjs v1v2.91.8. Attached patch needs to be applied.1.  Note that you have to install all the dependency packages before you proceed further.  Refer collaborate page for PhantomJS

git clone https://github.com/ariya/phantomjs.git
cd phantomjs
git checkout -b v2.1.91 2.8 1.9.8
git apply 0001-Patch-to-build-phantomjs-on-AArch64.patch
1
./build.shpy -c -confirm --jobs 4j $(getconf _NPROCESSORS_ONLN)

When the build is finished, create tar file for deployment

...

./bin/phantomjs test/run-tests.js

Install phantomjs-2.1.9.81-linux-aarch64.tar.bz2 to the system and add phantomjs to $PATH. Check if phantomjs is properly installed by doing:

ent-user@ambari-dk:~$ phantomjs --version
2.1.9.81

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.

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/release version. In our case this is 2.26.01. Patch is provided to make Ambari built on AArch64.  Apply all the patches before you are going for the build. You can directly clone and build my AMBARI git repository - https://git.linaro.org/people/naresh.bhat/apache/ambari.git

git clone https://gitgithub.linaro.orgcom/legapache/bigdata/ambari.git
cd ambari
git checkout release-2.6.1

Download and apply following patches

git am 0001-ambari-build-aarch64-2.4-aarch.6.1.patch
git am 0002-ambari-metrics-grafana-Add-jdeb-support.patch
git am 0003-ambari-funtest-Add-jdeb-support.patch
git am 0004-ambari-logsearch-Add-jdeb-support.patch
git am 0005-ambari-Add-jdeb-arm64-support.patch

mvn versions:set -DnewVersion=2.46.21.0.0
pushd ambari-metrics
mvn versions:set -DnewVersion=2.46.21.0.0
popd

On CentOS 7.4 to generate rpm's you can issue below command.

mvn -B clean install package rpm:rpm -DskipTests -Dpython.ver="python >= 2.6" -Preplaceurl -Drat.ignoreErrors=true

On Debian 9 to generate Debian packages you can issue below command.

mvn -B clean install jdeb:jdeb -DnewVersion=2.6.1.0.0 -DskipTests -Dpython.ver="python >= 2.6" -Drat.ignoreErrors=true 

Ambari Server will create following packages

...

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