Room For Improvement

Amazon EMR users face challenges with customization, stability, onboarding, cost optimization, task speed, and demand enhanced integration and security.
Cloudera Distribution for Hadoop struggles with stability and integration, needing better performance, security, documentation, and modern deployment solutions.
The cost factor differs significantly. When you run Spark application on EKS, you run at the pod level, so you can control the compute cost. But in Amazon EMR, when you have to run one application, you have to launch the entire EC2.
Senior Chief Engineer (Enterprise System Presales/Postsales) at a tech vendor with 10,001+ employees
I have thoughts on what would be great to see in the product, such as AI/ML features or additional options.
Senior Technical Engineer at a transportation company with 5,001-10,000 employees
There is room for improvement with respect to retries, handling the volume of data on S3 buckets, cluster provisioning, scaling, termination, security, and integration between services like S3, Glue, Lake Formation, and DynamoDB.
Lead AWS Data Engineer at Fission Labs
Integrating with Active Directory, managing security, and configuration are the main concerns.
Manager, Bussines Development & Co Owner at Troia d.o.o.
 

Setup Cost

Amazon EMR pricing is variable, potentially costly, but users can manage expenses with strategic resource and instance management.
Cloudera's Hadoop distribution is costly, aimed at large enterprises, lacking a community version, with per-node licensing.
Cost optimization can be achieved through instance usage, cluster sharing, and auto-scaling.
Lead AWS Data Engineer at Fission Labs
I would rate the price for Amazon EMR, where one is high and ten is low, as a good one.
Senior Technical Engineer at a transportation company with 5,001-10,000 employees
It can be deployed on-premises, unlike competitors' cloud-only solutions.

Data pipelines have simplified complex transformations and provide faster insights for users
The features at Amazon EMR that I have found most valuable are fully customizable functions. I am using Amazon EMR for data transformation, where we load the data. The entire ETL process is encompassed within it. The first thing is the egress part, where we pull the data from various sources, which include our main core databases, the systems that include Oracle, MySQL, SQL Server, and Postgres. We bring data from all these sources and use Amazon EMR specifically to combine all this data, clean the data, and combine it at a particular level. We bring everything to a particular level to make it more production-ready, and we simplify the data because every system has its own problems. We are using it to clean the data and transform the data in such a way that the end-user can get the insights faster.

Enables on-premise implementation with powerful data processing capabilities
This is the only solution that is possible to install on-premise. Cloudera provides a hybrid solution that combines compute on cloud or on-premises. It includes all machine learning algorithms in the Spark machine learning library. All functionalities needed for a big data platform and ETL are on the platform, eliminating the need for other tools. It is scalable, ready for vertical scaling, and very powerful, offering numerous functionalities and configurations for generative AI.
