Really amazing.

good

Logré comprender la funcionalidad y diferencias entre Hadoop y PySpark.

muy buena información, esperaría ampliaran un poco mas el temario.

This is a great starting point to know about this technology.

Good course..Last hands-on video was little blur

Very Interesting

The course covered basics of other topics such as python and dataframes, which are related, but not explicitly pyspark-specific. I also found the lecturer to be un-enthusiastic in their teaching style, most of the videos were just the lecturer reading from the slides and saying "like" or "right?" a lot, which was very distracting. The "hands on" portion was just watching the lecturer on a video go through motions very quickly without truly linking concepts together. I use pyspark in databricks and was hoping to elevate my use of it through this course. The only redeeming quality was the reading materials which I found helpful, but you could honestly just get that from the Apache Spark or Databricks help pages instead of here.

No puedo decir nada bueno de un curso en el que los conceptos están explicados con vaguedades y los ejemplos de código están apliados sin orden ni concierto. Podría entender conceptos explicados con generalidades si el volumen de conceptos a tratar fuesen muchos, pero no es el caso, explican 4 conceptos repetitivamente pero siempre con las mismas vaguedades. Primer curso que hago en coursera y primera decepción. Vale que la plataforma confie en las opiniones de los usuarios, pero tienen que hacer un filtro mínimo y descartar aquel contenido que cláramente no tenga una calidad mínima.

The instructor was hard to understand and the transcript was often incorrect. I didn't feel as though I learned what PySpark is and how it's different from Python in general. The instructor kept saying that it explained exactly what PySpark is and can do, but everything was extremely generic.

content was much more theoretical than expected more hands on experience for the learner would have been more engaging and fun.

This course was a frustrating and disappointing experience from start to finish. The instructor relied heavily on verbal fillers and repetitive phrases such as "like", "kind of," "pretty much," "so on and so forth", and frequently ended thoughts with "right?" This poor and unfocused delivery made it nearly impossible to glean any concrete information. By the end, almost nothing of substance was actually taught. It is an embarrassment that a course of this subpar quality is offered, and I would strongly advise against it for anyone looking to gain practical skills or real knowledge.

Too much theory and hardly any discussion on implementation.
