KNIME Big Data Extension

KNIME Big Data Extension
Leveraging your Hadoop Infrastructure
With the KNIME Big Data Extension, access to your data is now even easier. As part of the commercial KNIME.com AG offerings, the extension provides a set of nodes for accessing Hadoop/HDFS via Hive from inside KNIME Analytics Platform. It brings
with it all required libraries — after installing the extension from KNIME’s update website no additional steps are needed. The
Big Data Extension is certified by Cloudera for CDH 5.0.x and has also been tested against Hadoop 2.4.0 and Hive 0.13. The Big
Data Extension can be easily installed via the KNIME Update Manager.

KNIME Big Data Extension as part of a complete KNIME workflow
The Power of Hadoop
Mix and Match within KNIME
Cloudera Certified
KNIME allows you to take advantage of the power
of Hadoop from within your KNIME environment.
All Hive infrastructure features may be utilized
from the well documented and maintained
KNIME Analytics Platform.
The real power of Hadoop comes when you can
mix and match as needed across all steps of an
analytic application.
KNIME Big Data Extensions are Cloudera certified.
Building a Hadoop cluster from the ground up can
be challenging. There are numerous choices to be
made at all levels of the stack and making those
choices can be complex.
Database nodes may be combined with all features of KNIME, allowing advanced features like
flow variables and flow control to automate
which elements are executed at a given stage
within your Hadoop environment.
When combined with KNIME Server, you can go
even further to provide all types of access control
to your users, not only for the data but also for
the types of queries and manipulation that can be
performed.
With KNIME, you can mix data sources as well as
pick and choose exactly where a particular operation or task should complete, giving you total
control over the workflows that you build.
Starting with a subset of Hadoop data, KNIME
may be used to optimize exactly which portions
of the workflow application should be in Hadoop,
in another database, or in KNIME itself. You have
total control of your Big Data.
If you have KNIME Server, you can also surface all
or portions of the workflows to your casual users
via KNIME WebPortal, giving those users access
to sensible Big Data as well.
The Cloudera Certified Technology program is
designed to make selecting the right technology
easier. When you see the Cloudera Certified Technology logo, you can trust that the product has
been tested and validated to work with CDH,
Cloudera’s open source and enterprise-ready
distribution of Apache Hadoop and related projects.
KNIME Big Data Extensions are easy to use
Hive Connector
Hive Loader
Impala and more
The Hive Connector node establishes a connection
to a Hadoop/HDFS database. Connection details
may be specified and stored using the node dialog
box .
The Big Data Extension provides a special Hive
Loader node to get your data into Hadoop. The
node makes use of the File Handling extensions
and first copies the data to the HiveServer (using
SSH, FTP, or any other supported protocol ‒ note
that remote access to the HiveServer is currently
required). Next, a Hive command is executed to
import the data into Hadoop/HDFS. The node’s
output is a database connection operating on the
imported table.
Impala support will be added late in 2014. As with
all KNIME commercial products, enhancements to
KNIME Big Data Extension are automatically included as they become available.
Once executed, the node returns a database
connection that can be used with almost any of
KNIME’s standard database nodes.
You can easily upgrade to all new features via the
standard upgrade process built into your KNIME
Analytics Platform.
