Bikramjeet Vig resolved IMPALA-9077. ------------------------------------ Target Version: Impala 4.0 Resolution: Fixed > Fix scalable admission config for clusters with dedicated coordinators > ---------------------------------------------------------------------- > > Key: IMPALA-9077 > URL: https://issues.apache.org/jira/browse/IMPALA-9077 > Project: IMPALA > Issue Type: Bug > Affects Versions: Impala 3.3.0 > Reporter: Bikramjeet Vig > Assignee: Bikramjeet Vig > Priority: Major > > The scalable configs are: > Max Memory Multiple > Max Running Queries Multiple > Max Queued Queries Multiple > Currently the scalable configs scale based on number of total executors. This > can work for max running or queued queries multiple, but for "Max Memory > Multiple" this will cause the following problem: > Consider the following cluster composed of 2 dedicated coordinators and 2 > executors. For a regular query that will run on 2 executors and 1 > coordinator, if the memory to admit per backend is 100MB, the cluster memory > to be admitted will be 300MB. Now if the max_memory_multiple is 120MB this > query will not be admitted because the scalable max memory will be 120*2 = > 240. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
