I want to generate the spectrogram from the data in Hbase in Hortanworks Hdp? I got to know Matlab supports Hdp. So, anyone could please tell me how to do so? It will be a great help.
It's been a while since I worked with MATLAB, so I may not be much help - but here are some resources I found and also a place on HCC to ask where the respective experts may be able to weight in.

Data Processing Track on HCC (might be a good place to ask): https://community.hortonworks.com/spaces/66/index.html
