Hi all, A serious question.. I know this isn't one of the best hbase practices but I really want to know..
I am doing a join across 3 table in hbase.. One table contain 19m records, one contains 2m and another contains 1m records. I'm doing this inside the mapper function.. I know this can be done with pig and hive etc. Leaving the specifics out, how long would experts think it would take for the mapper to finish aggregating them across a 6 node cluster.. One is the job tracker and 5 are task trackers.. By the time I see the map reduce job status for input records reach 600,000 it's taking an hour.. It can't be right.. Any tips? Please help. Thanks. -- Regards- Pavan
