hi there, Need help / suggestion to formulate a hive-only best feasible/optimized strategy for:
- I have a table with list of reserved words - one word per row - I have a string wherein I want to search the presence of each reserve word and take a count of it .e.g: If there are 5 matches from my reserved keyword list , then I expect the query output to be 5. - I need to repeat this exercise recursively for all the 'sentences' in another table, that has one sentence per row. How should I do it to get the best (read quickest) performance without getting too much into recursion , using Hive. Advise/ suggestions requested. Environment details: Hive 0.14 / HDP 2.2 , CentOS 6.5 , 2 NN + 6 DN regards Devopam
