At Cloudera, there is a long and proud tradition of employees creating new open source projects intended to help fill gaps in platform functionality (in addition to hiring new employees who have done so in the past). In fact, more than a dozen ecosystem projects — including Apache Hadoop itself — were founded by Clouderans, more than can be attributed to employees of any other single company. Cloudera was also the first vendor to ship most of those projects as enterprise-ready bits inside its platform.
For several good reasons, 2013 is a Happy New Year for Apache Hadoop enthusiasts.
In 2012, we saw continued progress on developing the next generation of the MapReduce processing framework (MRv2), work that will bear fruit this year. HDFS experienced major progress toward becoming a lights-out, fully enterprise-ready distributed filesystem with the addition of high availability features and increased performance. And a hint of the future of the Hadoop platform was provided with the Beta release of Cloudera Impala,
It’s been an exciting month and a half since the launch of the Cloudera Impala (the new open source distributed query engine for Apache Hadoop) beta, and we thought it’d be a great time to provide an update about what’s next for the project – including our product roadmap, release schedule and open-source plan.
First of all, we’d like to thank you for your enthusiasm and valuable beta feedback. We’re actively listening and have already fixed many of the bugs reported,
We are happy to announce the general availability of CDH3 update 5. This update is a maintenance release of CDH3 platform and provides a considerable amount of bug-fixes and stability enhancements. Alongside these fixes, we have also included a few new features, most notable of which are the following:
- Apache Flume 1.2.0 – Provides a durable file channel and many more features over the previous release.
- Hive AvroSerDe – Replaces the Haivvreo SerDe and provides robust support for Avro data format.
Apache Flume is a scalable, reliable, fault-tolerant, distributed system designed to collect, transfer, and store massive amounts of event data into HDFS. Apache Flume recently graduated from the Apache Incubator as a Top Level Project at Apache. Flume is designed to send data over multiple hops from the initial source(s) to the final destination(s).
