Another possible improvement is to add alternatives check to the list of
current test?

> Key: BIGTOP-1335
> URL: https://issues.apache.org/jira/browse/BIGTOP-1335
> Project: Bigtop
> Issue Type: Improvement
> Components: Init scripts
> Reporter: Guo Ruijing
>
> In existing implementation, JAVA_HOME is automatically detected in
> /usr/lib/bigtop-utils/bigtop-detect-javahome if JAVA_HOME is not configured.
> If some component configure JAVA_HOME and some component doesn't configure
> JAVA_HOME by mistake, different component may use different JAVA_HOME. In
> this case, it is not easy to find JAVA_HOME difference in different
> components.
> We may improve:
> 1. WARNING message is generated if JAVA_HOME is not configured in
> /usr/lib/bigtop-utils/bigtop-detect-javahome.
> or 2. We may disable JAVA_HOME auto detection and use JAVA_HOME from
> /etc/default/bigtop-utils
