Bet you didn’t know this: In some cases, Solr offers lightning-fast response times for business-style queries.
If you were to ask well informed technical people about use cases for Solr, the most likely response would be that Solr (in combination with Apache Lucene) is an open source text search engine: one can use Solr to index documents, and after indexing, these same documents can be easily searched using free-form queries in much the same way as you would query Google.
Cloudera Search combines the speed of Apache Solr with the scalability of CDH. Our newest training course covers this exciting technology in depth, from indexing to user interfaces, and is ideal for developers, analysts, and engineers who want to learn how to effectively search both structured and unstructured data at scale.
Despite being nearly 10 years old, Apache Hadoop already has an interesting history. Some of you may know that it was inspired by the Google File System and MapReduce papers,
Security architecture is complex, but these testing strategies help Cloudera customers rely on production-ready results.
Among other things, good security requires user authentication and that authenticated users and services be granted access to those things (and only those things) that they’re authorized to use. Across Apache Hadoop and Apache Solr (which ships in CDH and powers Cloudera Search), authentication is accomplished using Kerberos and SPNego over HTTP and authorization is accomplished using Apache Sentry (the emerging standard for role-based fine grain access control,
Cloudera recently announced formal support for Apache Kafka. This simple use case illustrates how to make web log analysis, powered in part by Kafka, one of your first steps in a pervasive analytics journey.
If you are not looking at your company’s operational logs, then you are at a competitive disadvantage in your industry. Web server logs, application logs, and system logs are all valuable sources of operational intelligence,
An improved Search app in Hue 3.6 makes the Hadoop user experience even better.
Hue 3.6 (now packaged in CDH 5.1) has brought the second version of the Search App up to even higher standards. The user experience has been greatly improved, as the app now provides a very easy way to build custom dashboards and visualizations.
Below is a video demo-ing how to interactively explore some real Apache log data coming from the live Hue demo at cloudera.com/live.
