We have several customers in the energy business for whom we perform analysis services. Over the past couple of years we have made a few R models for them which allow them to input their data and receive an answer. We'd like to put this into a basic web application which: --Allows them to authenticate to gain access --Asks them to upload relevant input files --Allows them to be "checked" for issues (according to our tests) --Runs the R model --Prepares a csv for download The R model takes roughly 5 csv's as input, and produces 2 csv's as output (we have unit tests prepared which can help confirm accuracy during development).

We have a real time data processing setup using Storm trident and Kafka. The trident streams read data from kafka spouts and after processing, persists the data to titan db. We are currently running a single node cluster for both kafka and storm. The system runs for a while and then it gets stuck replaying a batch forever and no more data is processed there after. I need someone who can look into the system, understand the setup, provide the metrics from kafka and storm and above all resolve the above mentioned issue. If interested, please let me know and I would provide the more details.
