Do you use Tez session pool along with LLAP (as Thai suggests in the
previous reply)? If a new query finds an idle AM in Tez session pool, there
will be no launch cost for AM. If no idle AM is found or if you specify a
queue name, a new AM should start in order to serve the query. This is
The best approach would be to use a demonized containers such as Hive LLAP
+ Tez session pool or Spark on Hive.
I’m not that familiar with Spark on Hive so I can’t comment on it but Hive
on LLAP has worked really well for me when coupled with Tez session pool.
You’ll have to specify how many Tez
Hi All,
We have a use case where we need to return output in < 10 sec. We have
evaluated different set of tool for execution and they work find but they
do not cover all cases as well as they are not reliable(since they are in
evolving phase). But Hive works well in this context.
