The integration of Apache Sentry with Apache Solr helps Cloudera Search meet important security requirements.
As you have learned in previous blog posts, Cloudera Search brings the power of Apache Hadoop to a wide variety of business users via the ease and flexibility of full-text querying provided by Apache Solr. We have also done significant work to make Cloudera Search easy to add to an existing Hadoop cluster:
- It uses the same pool of data and system resources as other workloads,
Cloudera’s own enterprise data hub is yielding great results for providing world-class customer support.

Learn how to use Cloudera Search along with RBL-JE to search and index documents in multiple languages.
Our thanks to Basis Technology for providing the how-to below!
Basis Technology’s Rosette Base Linguistics for Java (RBL-JE) provides a comprehensive multilingual text analytics platform for improving search precision and recall. RBL provides tokenization, lemmatization, POS tagging, and de-compounding for Asian, European, Nordic, and Middle Eastern languages, and has just been certified for use with Cloudera Search.
You can use Hue and Cloudera Search to build your own integrated Big Data search app.
In a previous post, you learned how to analyze data using Apache Hive via Hue’s Beeswax and Catalog apps. This time, you’ll see how to make Yelp Dataset Challenge data searchable by indexing it and building a customizable UI with the Hue Search app.
Indexing Data in Cloudera Search
Indexing data in Cloudera Search involves :
- Setting up SolrCloud to partition your dataset into multiple indexes and processes
- Configuring SolrCloud collections to hold indexes
- Specifying the schema by which indexes will be created
- Feeding relevant data into the SolrCloud
Cloudera Manager 4.7 added support for managing Cloudera Search 1.0. Thus Cloudera Manager users can easily deploy all components of Cloudera Search (including Apache Solr) and manage all related services, just like every other service included in CDH (Cloudera’s distribution of Apache Hadoop and related projects).
In this how-to, you will learn the steps involved in adding Cloudera Search to a Cloudera Enterprise (CDH + Cloudera Manager) cluster.
