Subject [jira] [Commented] (CASSANDRA-2992) Cassandra doesn't start on Red Hat Linux due to hardcoded JAVA_HOME
Date Thu, 04 Aug 2011 14:51:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13079406#comment-13079406
] 

Taras Puchko commented on CASSANDRA-2992:
-----------------------------------------

No, CASSANDRA-2785 actually caused this bug, since now invalid JAVA_HOME is not ignored:
http://svn.apache.org/viewvc/cassandra/branches/cassandra-0.8/bin/cassandra?r1=1126728&r2=1152241&pathrev=1152241

But the real bug is setting JAVA_HOME to a fixed value in redhat specific scripts.

set correctly.

> The correct fix would be to remove "export JAVA_HOME" from /etc/init.d/cassandra or set
it only to correct path and only if it hasn't already been set.
> It would also be nice to revert to "[ -x $JAVA_HOME/bin/java ]" in /usr/sbin/cassandra
