HIVE table - Get records which are closest to a given numeric value
Question
From a hive table, I want records which are closest to a given value of each of the columns. Eg The table has columns - total_score, avg_score, etc. I want to get records which have total_score and avg_score close or equal to "a given value".
Note - Table has approx. 183 million rows and I want 1,50,000 records which are closest/equal to the given value of each of the columns.
Please help me with the process of doing it.
