David Rorke updated IMPALA-10036:
---------------------------------
Description:
Admission control rejected a query with the following error:
{noformat}
ERROR: Rejected query from pool root.default: request memory needed 50.00 GB is
greater than memory available for admission 45.36 GB of coordinator-0:22050.
{noformat}
The query profile shows the following resource estimates:
{noformat}
Per-Host Resource Estimates: Memory=303.36GB
Dedicated Coordinator Resource Estimate: Memory=136MB
{noformat}
The max query memory limit for the pool was configured as 50 GB.
Based on the coordinator resource estimate of 136 MB the query should have
easily fit in the available coordinator memory. [~tarmstrong] speculated that
we might simply be comparing the wrong resource estimate to the coordinator
limit.
Profile attached.
