Tim Armstrong created IMPALA-8119: ------------------------------------- Summary: Improve experience for configuring JVM heap size in docker container. Key: IMPALA-8119 URL: https://issues.apache.org/jira/browse/IMPALA-8119 Project: IMPALA Issue Type: Sub-task Components: Infrastructure Affects Versions: Impala 3.2.0 Reporter: Tim Armstrong Assignee: Tim Armstrong
The heap size can be configured via JAVA_TOOL_OPTIONS. Configuring the JVM heap size is likely a common task when deploying Impala containers to production because the catalogd and coordinators need to be sized to fit the working set of metadata - it would be worthwhile to have a more explicit and clearly-documented way to set the heap size. We could also try to be fancy and choose a heap size based on the container memory limit and the role of the container. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
