Hi,
I'm one of engieer of sina.com. We have used hive ,hiveserver several
months. We have our own tasks schedule system .The system can schedule tasks
running with hiveserver by jdbc.
But The hiveserver use mem very large, usally large than 10g. we have
5min tasks which will be running every 5 minutes.,and have hourly tasks .total
num of tasks is 40. And we start 3 hiveserver in one linux server,and be cycle
connected .
so why Memory of hiveserver using so large and how we do or some
suggestion from you ?
Thanks and Best Regards!
