Hadoop and Spark and Hive Installation

Downloading and installing Hadoop

Installing Hadoop 2.x to Red Hat Linux

This section including step by step procedures for installing

Hadoop 2.6.4

to Fedora 23, and configuring a Single Node Setup.

Step.1 Prerequisites

$ uname -a
Linux localhost 4.2.3-300.fc23.x86_64 #1 SMP Mon Oct 5 15:42:54 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

$ java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

Step.2 Download and Install

$ wget http://apache.fayea.com/hadoop/common/hadoop-2.6.4/hadoop-2.6.4.tar.gz $ tar -xvf hadoop-2.6.4.tar.gz
$ cd hadoop-2.6.4

Edit

/etc/profile

, root user is needed.

#set hadoop
export JAVA_LIBRARY_PATH=/home/renjie/work/hadoop/lib/native
export HADOOP_HOME=/home/userName/hadoop-2.6.4
export HADOOP_INSTALL=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin

After edit

source /etc/profile

Step.3 Configure

Edit

etc/hadoop/hadoop-env.sh

, comment out JAVA_HOME, make sure it point to a valid Java Home:

export JAVA_HOME=/usr/java/jdk1.7.0_60

NOTE: Java 1.6 or higher is needed.

Edit

etc/hadoop/core-site.xml

, add the following properties in :

<property>
<name>hadoop.tmp.dir</name>
<value>file:/home/userName/hadoop-2.6.4/tmp</value>
</property>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>hadoop.proxyuser.userName.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.userName.groups</name>
<value>*</value>
</property>

NOTE: the property’s value should match to your’s setting.

Edit

etc/hadoop/hdfs-site.xml

, add the following property in:

<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/home/userName/hadoop-2.6.4/tmp/dfs/name</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/home/userName/hadoop-2.6.4/tmp/dfs/data</value>
</property>

Format a new distributed-filesystem via execute

hadoop-2.6.4/bin/hadoop namenode -format

Step.4 Start

Start all hadoop services via execute

$ ./sbin/start-all.sh

NOTE: there are 5 java processes which represent 5 services be started:

NameNode

,

SecondaryNameNode

,

DataNode

,

JobTracker

,

TaskTracker

. Execute `jps -l’ to check the java processes:

$ jps -l
4056 org.apache.hadoop.hdfs.server.namenode.NameNode
4271 org.apache.hadoop.hdfs.server.datanode.DataNode
4483 org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode
4568 org.apache.hadoop.mapred.JobTracker
4796 org.apache.hadoop.mapred.TaskTracker

NOTE:

NameNode

,

JobTracker

,

TaskTracker

has relevant Web Consoles for View and Monitor the serivces. Web Access URLs for Services:

http://localhost:50030/   for the Jobtracker http://localhost:50070/   for the Namenode http://localhost:50060/   for the Tasktracker

Step.5 Stop

Stop all hadoop services via execute

# ./sbin/stop-all.sh

Downloading and installing Apache Hive

This section including step by step procedures for installing Apache Hive and set up HiveServer2.

Step.1 Prerequisites

Hadoop is the prerequisite, refer to above steps to install and start Hadoop.

Step.2 Install

$ tar -xvf apache-hive-1.2.1-bin.tar.gz
$ cd apache-hive-1.2.1-bin

Step.3 Configure

Create a

hive-env.sh

under

conf

$ cd conf/
$ cp hive-env.sh.template hive-env.sh
$ vim hive-env.sh

comment out HADOOP_HOME and make sure point to a valid Hadoop home, for example:

HADOOP_HOME=/home/kylin/server/hadoop-1.2.1

Navigate to Hadoop Home, create ‘/tmp’ and ‘/user/hive/warehouse’ and chmod g+w in HDFS before running Hive:

$ ./bin/hadoop fs -mkdir /tmp
$ ./bin/hadoop fs -mkdir /user/hive/warehouse
$ ./bin/hadoop fs -chmod g+w /tmp
$ ./bin/hadoop fs -chmod g+w /user/hive/warehouse
$ ./bin/hadoop fs -chmod 777 /tmp/hive

NOTE: Restart Hadoop services is needed, this for avoid

java.io.IOException: Filesystem closed

in DFSClient check Open.

Create a

hive-site.xml

file under conf folder

$ cd apache-hive-1.2.1-bin/conf/
$ touch hive-site.xml

Edit the

hive-site.xml

, add the following content:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hive.server2.thrift.min.worker.threads</name>
<value>5</value>
</property>
<property>
<name>hive.server2.thrift.max.worker.threads</name>
<value>500</value>
</property>
<property>
<name>hive.server2.thrift.port</name>
<value>10000</value>
</property>
<property>
<name>hive.server2.thrift.bind.host</name>
<value>0.0.0.0</value>
</property>
</configuration>

NOTE: there are other Optional properties, more refer to ]https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2[Setting+Up+HiveServer2]

Step.4 Start HiveServer2

$ ./bin/hiveserver2

Downloading and installing Apache Spark

This section including step by step procedures for installing Apache Spark in Single Node. You can install Spark from source or Pre-build package. In this section, we use Spark 1.6.1 Pre-built for Hadoop 2.6.

Spark runs on Java 7+, Python 2.6+ and R 3.1+. For the Scala API, Spark 1.6.1 uses Scala 2.10. You will need to use a compatible Scala version (2.10.x).

Step.1 Install Scala

1) Download Scala

$ wget http://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.tgz $ tar -zxvf scala-2.11.8.tgz

2)Configure

Edit

/etc/profile

, root user is needed.

export SCALA_HOME=/home/userName/scala-2.11.8
export PATH=$PATH:$SCALA_HOME/bin

After edit

source /etc/profile

Step.2 Install Spark

You will need to use a compatible Spark version to match Hadoop in your system.

1) Download Spark

You can download Spark from http://spark.apache.org/downloads.html.

$ tar -xvf spark-1.6.1-bin-hadoop2.6.tgz
$ cd spark-1.6.1-bin-hadoop2.6

2) Configure

Edit

/etc/profile

, root user is needed.

#set SPARK
export SPARK_HOME=/home/username/spark-1.6.1-bin-hadoop2.6
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin

After edit

source /etc/profile

Copy conf/spark-env.sh.template to conf/spark-env.sh, edit the

spark-env.sh

, add the following content:

export JAVA_HOME=/usr/local/java
export SCALA_HOME=/home/userName/scala-2.11.8
export SPARK_MASTER_IP=127.0.0.1
export SPARK_LOCAL_IP=127.0.0.1
export SPARK_WORKER_MEMORY=2000m
export HADOOP_CONF_DIR=/home/userName/hadoop-2.6.4/etc/hadoop
export SPARK_WORKER_CORES=1
export SPARK_WORKER_INSTANCES=1

Copy conf/slaves.template to conf/slaves, edit the

slaves

, add the following content:

localhost

Step.3 Start Spark

$ cd $SPARK_HOME
$ ./sbin/start-all.sh
