Tim Armstrong updated IMPALA-9772: ---------------------------------- Description: https://impala.apache.org/docs/build/html/topics/impala_mem_limit.html has some discussion about "cancelling queries" that is out of date > If query processing exceeds the specified memory limit on any node, either > the per-query limit or the impalad limit, Impala cancels the query > automatically. Memory limits are checked periodically during query > processing, so the actual memory in use might briefly exceed the limit > without the query being cancelled. This has been out-of-date for a long time. We already have a discussion of what actually happens in the spill-to-disk section here - https://impala.apache.org/docs/build/html/topics/impala_scalability.html "Usage notes" should probably refer to the admission control docs, which discusses how to configure memory resource management in detail - https://impala.apache.org/docs/build3x/html/topics/impala_admission.html The last bit of the example with the error is also very out of date - that query will either succeed reliably or be rejected by admission control because the memory limit is set too low. was:https://impala.apache.org/docs/build/html/topics/impala_mem_limit.html has some discussion about "cancelling queries" that is out of date > mem_limit docs are stale > ------------------------ > > Key: IMPALA-9772 > URL: https://issues.apache.org/jira/browse/IMPALA-9772 > Project: IMPALA > Issue Type: Documentation > Reporter: Tim Armstrong > Assignee: Tim Armstrong > Priority: Major > > https://impala.apache.org/docs/build/html/topics/impala_mem_limit.html has > some discussion about "cancelling queries" that is out of date > > If query processing exceeds the specified memory limit on any node, either > > the per-query limit or the impalad limit, Impala cancels the query > > automatically.
