Cloudera Sets Mission-critical Standards for Hadoop
Hadoop management tools have evolved over the time. Initially, it lacked the necessary integration and controlling capabilities. Hence, integrating into existing enterprise data infrastructures was an issue. However, the coexistence of Hadoop with its available resources provides truly comprehensive big data management.
These resources include –
- all existing systems
- platforms
- applications
- processes
Hence, customers faced issues regarding using data sets during mission-critical projects and gaining insight from it.
However, Cloudera and Hadoop are increasingly adopted as an integrated data repository to process the structured and unstructured data. Furthermore, it could be highly sensitive data which needs to maintain strict compliances.
Cloudera introduced its recent advancements to make Hadoop a complete big data platform. Cloudera offers data management features which follow data compliance and standard policy. This way Cloudera and Hadoop help in executing mission-critical applications.
Cloudera Manager 4.5 – An End to End Management Application

Is Your Work Safe?
The most popular objective of Hadoop is its ability to store data. It can store date at a much lower price than the logical database management software. Hence, it helps companies to use all their data to make better decisions.
However, Hadoop’s’ file system security level is not strong. Furthermore, it lacks the right support to guarantee secure data accessed by users and applications. Now this problem forces enterprises to stress upon security in different industries.
Not to mention, security is an essential need (like government, financial services, and healthcare).Either you can prevent users entirely or let data unprotected. Mostly, the best choice is the first, and this is inhibiting Hadoop of data access.
Sentry – Cloudera’s New Initiative for Security of Hadoop Data
Cloudera did not stop in improving Hadoop’s data security and launched Sentry. It is a new open source authorization technology that addresses these concerns. Sentry provides role-based authorization. It is required to provide specific levels of access to the right users and for the right applications. Along with the role-based approval, it supports a multi-tenant administration which allows Hadoop operators to:
- Store more data
- Give end-users access to that data
- Create new use cases
- Enable applications of multi-user
Based on the above, we intend to percolate Sentry to maximize its usefulness across the Hadoop ecosystem.
