What's relation between these two measurement? How do we use total ProcessingCost to find a suitable executor group? http://gerrit.cloudera.org:8080/#/c/19033/32/common/thrift/Frontend.thrift File common/thrift/Frontend.thrift: http://gerrit.cloudera.org:8080/#/c/19033/32/common/thrift/Frontend.thrift@779 PS32, Line 779: total CPU cores among all executor The max_mem_limit is defined as per host estimated-memory limit. We may define expected_num_cores as per host as well since we can get the size of executor group from curr_num_executors and expected_num_executors. -- To view, visit http://gerrit.cloudera.org:8080/19033 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: If32dc770dfffcdd0be2b5555a789a7720952c68a Gerrit-Change-Number: 19033 Gerrit-PatchSet: 32 Gerrit-Owner: Qifan Chen <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Kurt Deschler <[email protected]> Gerrit-Reviewer: Qifan Chen <[email protected]> Gerrit-Reviewer: Riza Suminto <[email protected]> Gerrit-Reviewer: Wenzhe Zhou <[email protected]> Gerrit-Comment-Date: Wed, 18 Jan 2023 00:45:47 +0000 Gerrit-HasComments: Yes
