Apache Bigtop – Installing Hive, HBase and Pig
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.

Step 5: Operations on Hive
HBase with Bigtop:
Installing Hbase is similar to Hive.
Step 1: Installing HBase
sudo apt-get install hbase\*
Step 2: Starting HMaster
sudo service hbase-master start
Step 3: Starting HBase shell
Step 4: HBase Operations
Pig with Bigtop:
Installing Pig is similar too.
Step 1: Installing Pig
sudo apt-get install pig
Step 2: Moving a file to HDFS
Step 3: Installed Pig-0.9.2
Step 4: Starting the grunt shell
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:

Bigtop’s KEYS file containing PGP keys we use to sign the release:
Let us see how to install other sub-projects in the coming posts!
Until then, Happy Learning!
