Test Steps

Install Pre-requisities

Clone the bigtop-trunk git repository and branch out to erp17.08

$ git clone https://git.linaro.org/leg/bigdata/bigtop-trunk.git
$ cd bigtop-trunk
$ git branch erp17.08 origin/erp17.08
$ git checkout erp17.08

Generate a docker image using build script in docker-puppet. This will create a docker image from aarch64/debian:jessie

$ cd docker/bigtop-puppet/debian-8-aarch64
$ sudo ./build.sh
$ sudo docker images
REPOSITORY          TAG                   IMAGE ID            CREATED             SIZE
bigtop/puppet       debian-8-aarch64     4b127acf355b        3 minutes ago       278.8 MB

$ cd <BIGTOP_SRC_TOP>
$ docker build -t bigtop/slaves:erp17.08-debian-8-aarch64 -f docker/bigtop-slaves/debian-8-aarch64/Dockerfile .

Basic packages are required for all big data components. They are: bigtop-groovy, bigtop-utils, bigtop-jsvc and bigtop-tomcat

$ sudo docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew bigtop-groovy-deb bigtop-utils-deb bigtop-jsvc-deb bigtop-tomcat-deb'

Build the target BigTop components like Hadoop, Hbase, Spark and Hive debian and packages

$ sudo docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew hadoop-deb hbase-deb spark-deb hive-deb'
$ sudo docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew hadoop-pkg hbase-pkg spark-pkg hive-pkg'

Build smoke test dependent packages

$ sudo docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew flume-deb mahout-deb pig-deb sqoop-deb zookeeper-deb'

Create a local repo

$ sudo docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew apt'

Create smoke test configuration file.

Bigtop smoke test uses yaml to configure test repo/environment/components. A typical configuration yaml can be found at <BIGTOP_SRC_TOP>/provisioner/docker/erp17.08-debian-8-aarch64

Generally following properties should be customized for certain smoke test:

docker image
repo url
distro type
components to install
components to test

Following is configuration yaml for Hive:

docker:
        memory_limit: "4g"
        image:  "bigtop/puppet:debian-8-aarch64"

repo: "http://bigtop-repos.s3.amazonaws.com/releases/1.2.0/debian/8-aarch64/aarch64"
distro: debian
components: [hdfs, yarn, mapreduce, hive]
enable_local_repo: true
smoke_test_components: [hive]
jdk: "openjdk-8-jdk"

Execute smoke tests

It is quite straight forward to execute smoke in bigtop

cd provisioner/docker
./docker-hadoop.sh -C <smoke_test_cfg_yaml> -c <node_count> -s -d

for example:
# ./docker-hadoop.sh -C config_debian-8-aarch64.yaml -c 3 -s -d

Before running smoke test, it is suggested to run environment check first

./docker-hadoop.sh -E

For detailed usage, just issue: ./docker-hadoop.sh

usage: docker-hadoop.sh [-C file ] args
       -C file                                   Use alternate file for config.yaml
  commands:
       -c NUM_INSTANCES, --create NUM_INSTANCES  Create a Docker based Bigtop Hadoop cluster
       -d, --destroy                             Destroy the cluster
       -e, --exec INSTANCE_NO|INSTANCE_NAME      Execute command on a specific instance. Instance can be specified by name or number.
                                                 For example: docker-hadoop.sh --exec 1 bash
                                                              docker-hadoop.sh --exec docker_bigtop_1 bash
       -E, --env-check                           Check whether required tools has been installed
       -l, --list                                List out container status for the cluster
       -p, --provision                           Deploy configuration changes
       -s, --smoke-tests                         Run Bigtop smoke tests
       -h, --help

To run the Spark smoke tests you need to apply 2 patches https://issues.apache.org/jira/browse/BIGTOP-2860 and https://issues.apache.org/jira/browse/BIGTOP-2866

$ vim provisioner/docker/config_debian-8-aarch64.yaml

Do the below changes

components: [hdfs, yarn, mapreduce, hive, spark]
enable_local_repo: true
smoke_test_components: [spark]
jdk: "openjdk-8-jdk"

save and quit.

$ vim provisioner/utils/smoke-tests.sh

Add the below lines

export HADOOP_HOME=/usr/lib/hadoop
export HADOOP_PREFIX=$HADOOP_HOME
export HADOOP_OPTS="-Djava.library.path=$HADOOP_PREFIX/lib/native"
export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec
export HADOOP_CONF_DIR=/etc/hadoop/conf
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_MAPRED_HOME=/usr/lib/hadoop-mapreduce
export HADOOP_HDFS_HOME=/usr/lib/hadoop-hdfs
export YARN_HOME=/usr/lib/hadoop-yarn
export HADOOP_YARN_HOME=/usr/lib/hadoop-yarn/
export HADOOP_USER_NAME=hdfs
export CLASSPATH=$CLASSPATH:.
export CLASSPATH=$CLASSPATH:$HADOOP_HOME/hadoop-common-2.7.2.jar:$HADOOP_HOME/client/hadoop-hdfs-2.7.2.jar:$HADOOP_HOME/hadoop-auth-2.7.2.jar:/usr/lib/hadoop-mapreduce/*:/usr/lib/hive/lib/*:/usr/lib/hadoop/lib/*:
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")
export PATH=/usr/lib/hadoop/libexec:/etc/hadoop/conf:$HADOOP_HOME/bin/:$PATH
export SPARK_HOME=/usr/lib/spark
export PATH=$HADOOP_HOME\bin:$PATH
export SPARK_DIST_CLASSPATH=$HADOOP_HOME\bin\hadoop:$CLASSPATH:/usr/lib/hadoop/lib/*:/usr/lib/hadoop/lib/*:/usr/lib/hadoop-mapreduce/*:.
export CLASSPATH=$CLASSPATH:/usr/lib/hadoop/lib/*:.

export SPARK_HOME=/usr/lib/spark
export SPARK_MASTER_IP=172.17.0.2
export SPARK_MASTER_PORT=7077

save and quit.

Run the command smoke test commands

$ ./docker-hadoop.sh -C config_debian-8-aarch64.yaml -c 3 -s -d

If the smoke test is still failing.  It might be because of you have't set the "SPARK_MASTER_IP" properly.  Another way to do is that remove the $masterMode and add local[*] as below

$ vim bigtop-tests/smoke-tests/spark/TestSpark.groovy

make the below change

final String SPARK_SHELL = SPARK_HOME + "/bin/spark-shell --master local[*]"

save and quit. Now run the spark smoke-tests again.

Using sandbox

$ cd docker/sandbox
If you are pointing to any other image e.g. the image located on your local git hub, you can edit the build script and change the "FROM bigtop/puppet:${OS}"
$ sudo ./build.sh -a bigtop -o debian-8-aarch64 -c "hadoop, spark, hive, hbase"

How to Tag and Export bigtop-puppet docker image in your own area. You need to create an account on https://hub.docker.com/ following are the example commands

$ sudo docker tag 4b127acf355b nbhat/puppet:debian-8-aarch64
$ sudo docker login 
$ sudo docker push nbhat/puppet:debian-8-aarch64

How to create bigtop-slaves image using the image in your area

$ cd  docker/bigtop-slaves/debian-8-aarch64
$ vim Dockerfile

Change the image fetching path in Dockerfile for example: "FROM bigtop/puppet:debian-8-aarch64" to "FROM nbhat/puppet:debian-8-aarch64" 
Note that the image must be available on my area at https://hub.docker.com/
