--------------------------------------
Summary: Cannot manually set both JAVA_HOME and IMPALA_JAVA_TARGET
Key: IMPALA-14450
URL: https://issues.apache.org/jira/browse/IMPALA-14450
Project: IMPALA
Issue Type: Task
Components: Frontend
Affects Versions: Impala 5.0.0
Reporter: Michael Smith
As we work to support Java 17, a problem that's come up is that when you set
{{IMPALA_JAVA_HOME_OVERRIDE}} to specify your own {{JAVA_HOME}}, it overrides
{{IMPALA_JDK_VERSION}}. If you happen to source bin/impala-config.sh in the
same shell, then {{IMPALA_JAVA_TARGET=override}} and compilation fails.
In more specific environments with subshells, this isn't necessarily a problem
until you try to provide {{IMPALA_JDK_VERSION}} as an environment variable. By
declaring the environment variable, the update {{IMPALA_JDK_VERSION=override}}
escapes the subshell and breaks subsequent build steps.
