Apache Bigtop – Installing Hive, HBase and Pig

In the previous post we learnt how easy it was to install Hadoop with Apache Bigtop!
We know its not just Hadoop and there are sub-projects around the table! So, lets have a look at how to install Hive, Hbase and Pig in this post.

Before rowing your boat…

Please follow the previous post and get ready with Hadoop installed!
Follow the link for previous post:

also, the same can be found at DZone, developer site: http://www.dzone.com/links/hadoop_hangover_introduction_to_apache_bigtop_and.html

All Set?? Great! Head On..
Make sure all the services of Hadoop are running. Namely, JobTracker, SecondaryNameNode, TaskTracker, DataNode and NameNode. [standalone mode]

Hive with Bigtop:

The steps here are almost the same as Installing Hive as a separate project.
However, few steps are reduced.
The Hadoop installed in the previous post is Release 1.0.1

We had installed Hadoop with the following command

sudo apt-get install hadoop\*
                    

Step 1: Installing Hive

We have installed Bigtop 0.3.0, and so issuing the following command installs all the hive components.
ie. hive, hive-metastore, hive-server. The daemons names are different in Bigtop 0.3.0.

sudo apt-get install hive\*

This installs all the hive components. After installing, the scripts must be able to create /tmp and /usr/hive/warehouse and HDFS doesn’t allow these to be created while installing as it is unaware of the path to Java. So, create the directories if not created and grant the execute permissions.
In the hadoop directory, ie. /usr/lib/hadoop/

bin/hadoop fs -mkdir /tmp
bin/hadoop fs -mkdir /user/hive/warehouse
bin/hadoop -chmod g+x /tmp
bin/hadoop -chmod g+x /user/hive/warehouse

Step 2: The alternative directories could be /var/run/hive and /var/lock/subsys

sudo mkdir /var/run/hive
sudo mkdir /var/lock/subsys

Step 3: Start the hive server, a daemon

sudo /etc/init.d/hive-server start

Step 4: Running Hive
Go-to the directory /usr/lib/hive.
See the Image below:
bin/hive

Step 5: Operations on Hive

HBase with Bigtop:

Installing Hbase is similar to Hive.

Step 1: Installing HBase

sudo apt-get install hbase\*

Image:

Step 2: Starting HMaster

sudo service hbase-master start

Image:

Image:

Step 3: Starting HBase shell

hbase shell

Step 4: HBase Operations

Pig with Bigtop:

Installing Pig is similar too.

Step 1: Installing Pig

sudo apt-get install pig

Image:

Step 2: Moving a file to HDFS
Image:

Step 3: Installed Pig-0.9.2
Image:

Step 4: Starting the grunt shell

pig

Step 5: Pig Basic Operations

We saw that is it possible to install the subprojects and work with Hadoop, with no issues.
Apache Bigtop has its own spark! :)

There is a release coming BIGTOP-0.4.0 which is supposedly to fix the following issues:

https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12318889&styleName=Html&projectId=12311420

Source and binary files:

http://people.apache.org/~rvs/bigtop-0.4.0-incubating-RC0

Maven staging repo:

https://repository.apache.org/content/repositories/orgapachebigtop-279

Bigtop’s KEYS file containing PGP keys we use to sign the release:

http://svn.apache.org/repos/asf/incubator/bigtop/dist/KEYS

Let us see how to install other sub-projects in the coming posts!
Until then, Happy Learning!
