Big data technologies have grown tremendously in past few years fueled by the dedicated research support from the open source communities. The ideas around Big Data are not buzz anymore. Industry-wide adoption has been phenomenal which led to the increase in demand but scarcity in supply of talented professionals in this field. However, jump on the bandwagon behavior has created more semi-skilled people and few who has in-depth command on these technologies.

Plethora of online resources are available to teach the concepts in depth and more so now it is also possible to work on such technologies without needing any costly licenses. Cloudera and hortonworks provide access to their cluster distribution without any cost for someone to get hands-on experience with distributed computing. MapR has a collection of very good tutorial available freely on their website. Anyone can register for their courses to get acquaintance with hadoop and spark frameworks. This is not true for propriety technologies such as SAP HANA which is a in-memory computation framework. HANA learning curve is more flatter as the resources are often very costly.

In addition to continually learning and practicing these technologies it is also critical to test your expertise. This is where renowned certifications come into the picture. Certifications not just test your knowledge but also provide you confidence on the subject. The institutions that run these certifications do a lot of research and keep upgrading the topics to match technological changes. The questions are very challenging and not just always multiple choice but sometimes also require working on the software. Cloudera, Hortonworks and HP Vertica certifications require you to work on the live clusters. All of these certification are available in web-based proctored testing  format online except for SAP certified application associate certification.
