Hive: All content tagged as Hive in NoSQL databases and polyglot persistence
Just found slideck (embedded below) describing the data workflow at Klout. Their architecture includes many interesting pieces combining both NoSQL and relational databases with Hadoop and Hive and Pig and traditional BI. Even Excel gets a mention in the slides:
- Pig and Hive
- Elastic Search
The post is a bit old, but the data contained comparing different compression methods is helpful:

Hortonworks has announced the 1.0 release of the Hortonworks Data Platform prior to the Hadoop Summit 2012 together with a lot of supporting quotes from companies like Attunity, Dataguise, Datameer, Karmasphere, Kognitio, MarkLogic, Microsoft, NetApp, StackIQ, Syncsort, Talend, 10gen, Teradata, and VMware.
Some info points:
Hortonworks Data Platform is a platform meant to simplify the installation, integration, management, and use of Apache Hadoop
- HDP 1.0 is based on Apache Hadoop 1.0
- Apache Ambari is used for installation and provisioning
- The same Apache Amabari is behind the Hortonworks Management Console
- For Data integration, HDP offers WebHDFS, HCatalog APIs, and Talend Open Studio
- Apache HCatalog is the solution offering metadata and table management
Hortonworks Data Platform is 100% open source—I really appreciate Hortonworks’s dedication to the Apache Hadoop project and open source community
- HDP comes with 3 levels of support subscriptions, pricing starting at $12500/year for a 10 nodes cluster
One of the most interesting aspects of the Hortonworks Data Platform release is that the high-availability (HA) option for HDP is based on using VMWare-powered virtual machines for the NameNode and JobTracker. My first thought about this approach is that it was chosen to strengthen a partnership with VMWare. On the other hand, Hadoop 2.0 contains already a new highly-available version of the NameNode (Cloudera Hadoop Distribution uses this solution) and VMWare has bigger plans for a virtualization-friendly Hadoop environment with project Serengeti.

The primary goal of Bigtop is to build a community around the packaging and interoperability testing of Hadoop-related projects. This includes testing at various levels (packaging, platform, runtime, upgrade, etc…) developed by a community with a focus on the system as a whole, rather than individual projects.
- Apache Hadoop 1.0.x
- Apache Zookeeper 3.4.3
- Apache HBase 0.92.0
- Apache Hive 0.8.1
- Apache Pig 0.9.2
- Apache Mahout 0.6.1
- Apache Oozie 3.1.3
- Apache Sqoop 1.4.1
- Apache Flume 1.0.0
- Apache Whirr 0.7.0
Apache Bigtop looks like the first step towards the Big Data LAMP-like platform analysts are calling for. Practically though it’s goal is to ensure that all the components of the wide Hadoop ecosystem remain interoperable.

Just 19 slides, but Paul Lam manages to provide both a comparison of Cascalog and Hive, plus an overview of the most interesting bits of Cascalog.
Cascalog vs Hive
Cascalog Query Pipe Assembly
Highly recommended for understanding what’s in the Cascalog box.
Edd Dumbill enumerates the various components of the Hadoop ecosystem:
