ENTRIES TAGGED "hive"
OSCON 2013 Speaker Series
If you have delved into Apache Hadoop and related projects, you know that installing and configuring Hadoop is hard. Often, a minor mistake during installation or configuration with messy tarballs will lurk for a long time until some otherwise innocuous change to the system or workload causes difficulties. Moreover, there is little to no integration testing among different projects (e.g. Hadoop, Hive, HBase, Zookeeper, etc.) in the ecosystem. Apache Bigtop is an open source project aimed at bridging exactly those gaps by:
1. Making it easier for users to deploy and configure Hadoop and related projects on their bare metal or virtualized clusters.
2. Performing integration testing among various components in the Hadoop ecosystem.
More about Apache Bigtop
The primary goal of Apache 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.
The latest released version of Apache Bigtop is Bigtop 0.5 which integrates the latest versions of various projects including Hadoop, Hive, HBase, Flume, Sqoop, Oozie and many more! The supported platforms include CentOS/RHEL 5 and 6, Fedora 16 and 17, SuSE Linux Enterprise 11, OpenSuSE 12.2, Ubuntu LTS Lucid and Precise, and Ubuntu Quantal.
Who uses Bigtop?
Folks who use Bigtop can be divided into two major categories. The first category of users are those who leverage Bigtop to power their own Hadoop Distributions. The second category of users are those who use Bigtop for deployment purposes.
In alphabetical order, they are:
Some organizations create their own real-time analysis tools, while others turn to specialized solutions. In a previous post, I highlighted SQL-based real-time analytic tools that can handle large amounts of data. I noted that other big data management systems such as MPP databases and MapReduce/Hadoop were too batch-oriented to deliver analysis in near real-time. At least for MapReduce/Hadoop systems things may have changed slightly. A group of researchers from UC Berkeley and Yahoo recently modified MapReduce to allow for pipelining between operators.
The growing need to manage and make sense of Big Data, has led to a surge in demand for analytic databases, which many companies are attempting to fill. As an alternative to current shared-nothing analytic databases, HadoopDB is a hybrid that combines parallel databases with scalable and fault-tolerant Hadoop/MapReduce systems.
