[jira] [Commented] (BIGTOP-1012) bigtop-detect-javahome should
check PATH if JAVA_HOME is unset
[ https://issues.apache.org/jira/browse/BIGTOP-1012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13879807#comment-13879807 ]
Tsuyoshi OZAWA commented on BIGTOP-1012:
----------------------------------------
+1 for the change(non binding). JDK can be install anywhere. This is a log when we faced a problem by using bigtop-detect-javahome.

> Issue Type: Bug
> Reporter: Rick Schultz
>
> Even in cases where java is in a user's $PATH, bigtop-detect-javahome will only check a fixed list of locations and leave JAVA_HOME unset if java is installed somewhere else. Folks who install a non-distro JRE/JDK are likely to put it into /usr/local or /opt and modify PATH appropriately.
> Other projects (cf. FLUME-1154) are working around this in their own init scripts. This should be handled centrally within the bigtop-detect-javahome script itself.
