-------------------------------------
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.
