This new version eliminates a lot of the scripting work needed by providing tools to get the data into Hadoop, to reorganize the data once in Hadoop, and to export the resulting data set back out again. After the material is organized, it then must be exported back out to a data warehouse or database in a easily-accessible format. This “sessionization process,” can involve 40 or more steps. The data must be put into the Hadoop file system, and then reorganized by each individual’s session. “Collecting clickstream data from 2,000 servers is not trivial,” he said.

The source data for clickstream tracking comes from activity logs of multiple servers. He offered an example of how these additional tools could help speed clickstream analysis, which involves building records of how users click through different Web sites. The new distribution can streamline a lot of the work required to set up Hadoop jobs, Zedlewski said. It is particularly well-suited for processing and analyzing vast amounts machine-generated data that can’t fit into standard relational databases. All the tools are open source, under the Apache Foundation license.įirst developed as an offshoot of the Apache Lucene search engine, Hadoop is a framework for processing large amounts of data scattered across multiple nodes. The new package includes additional programs such as a data aggregation tool called Flume, the data format converter called Sqoop, a Hadoop graphical user interface called Hue, and a configuration tool called the Zookeeper.

The core Hadoop package itself contains the MapReduce distributed workforce engine, the Hadoop Distributed File System (HDFS), and a set of assorted tools called Hadoop Commons.

The prior version of Cloudera’s package included the core Hadoop programs, the Hive data warehouse software and the Pig data flow scripting language. “People will want to consume a complete system that has all been tested and integrated together,” Zedlewski said. With version 3 of its Hadoop package, CHD3, Cloudera has added and integrated seven additional programs, all of which should help smooth the process of setting up and running Hadoop jobs, Zedlewski asserted. There is this whole ecosystem of other open source components that collectively make up the whole Hadoop ecosystem that people run in production today,” said Cloudera vice president of products Charles Zedlewski. “What we saw was that most organizations deploy quite a bit more than just Hadoop. With the new release of its Hadoop distribution, Cloudera has radically expanded the set of supporting tools for the data processing framework.
