-----------------------------------
Summary: JAVA_HOME auto detect improvement
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
