hi all, i'm writting a program to access my hbase table in a MR job. my first version is to get different values from get(row,column name), and now im changing to get one row each time into a map, and query that map instead - for one reduce job. i think it would be better to access hbase only once per one reduce function, but it seems like the latter version takes a longer time to finish
during the reduce job. does this mean get(row, column name) is less expensive than get(row) ? thanks. Daniel
