-------------------------------------
Summary: Set
hive.llap.memory.oversubscription.max.executors.per.query to be 1/3rd of num of
llap daemons
Key: HIVE-20560
URL: https://issues.apache.org/jira/browse/HIVE-20560
Project: Hive
Issue Type: Improvement
Components: Hive
Reporter: Miklos Gergely
Fix For: 4.0.0
Unless hive.llap.memory.oversubscription.max.executors.per.query is not
specified by the user,
it should be calculated like this:
{noformat}
hive.llap.memory.oversubscription.max.executors.per.query = min(max(1,
int(0.33*hive.llap.daemon.num.executors)),8)
{noformat}
In container mode it remains 3 (unless specified otherwise).
