HDP 2.1 tutorials from Hortonworks :

The quality you have come to expect from Hortonwork tutorials but the data sets are a bit dull.

What data sets would you suggest to spice up this tutorials?

Hortonworks Data Platform 2.1

Filed under: Apache Ambari,Falcon,Hadoop,Hadoop YARN,Hive,Hortonworks,Knox Gateway,Solr,Storm,Tez — Patrick Durusau @ 2:49 pm

Hortonworks Data Platform 2.1 by Jim Walker.

From the post:

The pace of innovation within the Apache Hadoop community is truly remarkable, enabling us to announce the availability of Hortonworks Data Platform 2.1, incorporating the very latest innovations from the Hadoop community in an integrated, tested, and completely open enterprise data platform.

A VM available now, full releases to follow later in April.

Just grabbing the headings from Jim’s post:

The Stinger Initiative: Apache Hive, Tez and YARN for Interactive Query

Data Governance with Apache Falcon

Security with Apache Knox

Stream Processing with Apache Storm

Searching Hadoop Data with Apache Solr

Advanced Operations with Apache Ambari

See Jim’s post for some of the details and the VM for others.

Securing Hadoop with Knox Gateway

Filed under: Hadoop,Knox Gateway,Security — Patrick Durusau @ 9:23 pm

Securing Hadoop with Knox Gateway by Kevin Minder

From the post:

Back in the day, in order to secure a Hadoop cluster all you needed was a firewall that restricted network access to only authorized users. This eventually evolved into a more robust security layer in Hadoop… a layer that could augment firewall access with strong authentication. Enter Kerberos. Around 2008, Owen O’Malley and a team of committers led this first foray into security and today, Kerberos is still the primary way to secure a Hadoop cluster.

Fast-forward to today… Widespread adoption of Hadoop is upon us. The enterprise has placed requirements on the platform to not only provide perimeter security, but to also integrate with all types of authentication mechanisms. Oh yeah, and all the while, be easy to manage and to integrate with the rest of the secured corporate infrastructure. Kerberos can still be a great provider of the core security technology but with all the touch-points that a user will have with Hadoop, something more is needed.

The time has come for Knox.

Timely news of an effort at security that doesn’t depend upon obscurity (or inner circle secrecy).

Hadoop installations, in topic map flow flow and not, need to pay attention to this project.
