I went through the Big data and the hadoop course .
The plus side -
1> The educator was very senior
2> He was slow and used to explain clearly .
3> The course covered all the topics .
The minus side -

The map reduce examples were not explained clearly with respect to what each java pharse meant and number of examples that was explained . having that said pig and hive examples were well explained .
I had a decent experience with hadoop and big data hope to have the same with spark
