--------------------------------------
Assignee: Michael Smith
> 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
> Assignee: Michael Smith
> Priority: Major
>
> 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.
