> we are building ms sql cube by linkedserver connectiong hiveserver with Cloudera's ODBC
driver.
> There are two test results:
> 1. hiveserver1 running on 2CPUs, 8G mem, took about 8 hours
> 2. hiveserver2 running on 4CPUs, 16 mem, took about 13 hours and 27min (never successful
on machine with 2CPUs, 8G mem)
>  Although on both cases, almost all CPUs are busy when building cube.
> But I cannot understand why hiveserver2 is much slower than hiveserver1, because from
doc, hs2 support concurrency, it should be faster than hs1, isn't it?
>  
> Thanks.

> CDH4.3 on CentOS6.
