Summary: Fix bogus too-high memory estimates
Key: IMPALA-7353
URL: https://issues.apache.org/jira/browse/IMPALA-7353
Project: IMPALA
Issue Type: Sub-task
Components: Frontend
Reporter: Tim Armstrong
Assignee: Bikramjeet Vig
Some operators have bogus memory estimates that are probably way too high. We
should adjust them to be a little more realistic.
E.g. in HBaseScanNode:
{code}
@Override
public void computeNodeResourceProfile(TQueryOptions queryOptions) {
// TODO: What's a good estimate of memory consumption?
nodeResourceProfile_ = ResourceProfile.noReservation(1024L * 1024L *
1024L);
}
{code}
