Ask HN: How to achieve reporting from the RDF data stored in HBASE?

We have an application where we are storing all information as RDF triples in HBase. Now we need to do data analysis and make reports out of it. The current approach is, we are extracting a part of data according to the need of reporting using map reduce and dump that data to a .tsv file and use that file for reporting. But the problem with this approach is : 1. The extracts run for a long time as it needs to traverse through all customers in HBase and give out put for reporting. As a result, for single requirement , we need to wait for a long time. Though the performance can be made better using a good hardware configuration. Still it takes ~10 hrs to pass through all data. We do have Time constraint. 2. Sometimes, the data is so huge that, we can't use MS excel for creating charts. So we use shell script to divide the data, but we need some tool to handle this huge data to create charts 3. Now the final objective is to show the reports or to create an interactive dashboard (containing filters with charts) Guys, Can you please suggest any solution for above problems?
