Bryan and Vivek from Rapleaf invited me to talk at there hadoop event this Tuesday. Thanks again.
I presented a experience report of a in production system we build over the last year with hadoop and katta (lucene the grid style). It was a fun event and quite a lot of people showed up.
Here you find my katta, pig and hadoop in production – experience report slides .
