> ------------------------------------------------------
> Bug filed by "grep.alex" at 
> http://getsatisfaction.com/cloudera/topics/cdh3b3_zookeeper_startup_script_doesnt_use_java_home
> On RedHat 5 (using the RPM installer) I was able to install and run all the 
> Hadoop components. The Zookeeper install was fine, but it wouldn't start:
> {noformat}
> [root@aholmes-desktop init.d]# ./hadoop-zookeeper start 
> JMX enabled by default 
> Using config: /etc/zookeeper/zoo.cfg 
> Starting zookeeper ... 
> STARTED 
> [root@aholmes-desktop init.d]# Exception in thread "main" 
> java.lang.NoSuchMethodError: method 
> java.lang.management.ManagementFactory.getPlatformMBeanServer with signature 
> ()Ljavax.management.MBeanServer; was not found. 
> at 
> org.apache.zookeeper.jmx.ManagedUtil.registerLog4jMBeans(ManagedUtil.java:48 
> ...
> {noformat} 
> After some digging around I found the cause - the Zookeeper startup script 
> (/usr/lib/zookeeper/bin/zkServer.sh ) uses the java found in the path, 
> whereas the other startup scripts use JAVA_HOME. In my case I had the default 
> RHEL5 1.4 JDK in the path, and the 1.6 JDK RPM's installed under /usr/java, 
> hence the above error, which I'm guessing is a fairly common setup.
> In my opinion all the startup scripts should all use the same mechanism to 
> determine where to pick java.
