Amazon EMR

Amazon Elastic MapReduce is useful in cases where two conditions are met. First, that you are planning on using multiple big data tools simultaneously to analyze big data sets. And second, that you need a tool that simplifies managing big data tools. If these two conditions are met, MapReduce does a great job. The user interface is simple. The program eliminates some programming requirements. The software also makes setting up big data analyses much easier. With these benefits acknowledged, MapReduce is not a good tool for "small" data analyses, given that there are other tools that do the job quicker and much more professional output. If you're on the fence, try out MapReduce with competing "small" data tools and see if you really need big data software.

Cloudera Enterprise Data Hub

CDH is not a replacement of RDBMS, we should think it as complementary technologies to DWH systems. CDH can be used for data lake and reduces costs too much.

Pros

  • Ease of use and ease to setup
  • Autoscaling functionality
  • Integrated into the AWS environment

  • Massive amounts of data consumption. It is fairly easy to implement and understand how to manage a Hadoop cluster.
  • Cloudera makes the management of a cluster much easier than installing and managing it with the pure Apache version.

Cons

  • Cost overhead is a bit high
  • Limited versions of frameworks that can be used

  • Some of the previous versions have compatibility issues with latest CentOS Virtual machines. So you have to take care of the Cloudera product's versions as well as CentOS version.
  • Compatibility issues with installation on Mac. Everything is Linux based so user has to have good knowledge of Linux commands.
  • GUI's are missing
  • I ended up spending time on matching the exact Cloudera product version with CentOS version. So had invested a lot of time in installtion/uninstallation of these products until u match/find the exact version. I had issues while installing Impala maybe it was new when i had a chance to work on Cloudera Impala.

Being a student I just evaluated it in lab, so not sure when I would buy, but would be potential buyer in future.

Alternatives Considered

The alternatives to EMR are mainly hadoop distributions owned by the 3 companies above. I have not used the other distributions so it is difficult to comment, but the general tradeoff is, at the cost of a longer setup time and more infra management, you get more flexible versioning and potentially faster access to newer versions of some frameworks such as Spark.

It was selected for lab testing and definitely have positive experience.

Return on Investment

  • Amazon Elastic MapReduce has had a positive ROI in the sense that it saved time managing big data projects where analysts were using different big data tools. Essentially, an increase in employee productivity.
  • Elastic MapReduce is not worth it in cases where you're just trying things out. You'll likely lose money unless you're sure that using MapReduce is a good idea.
  • Elastic MapReduce takes some time learning, although not too much. If the employee is less well-versed in big data analytics, the software is a high hill to climb that eats up employee time.

  • Definitely faster setup/management time. Could not comment on ROI, as tested in lab setup.
