Re: Error: JAVA_HOME is not set and Java could not be found

I have installed and configured 2 hosts.One host installed oracle-j2sdk1.7  java-1.7.0-openjdk cloudera-manager-daemons cloudera-manager-server and  cloudera-manager-server-db-2,another host installed cloudera-manager-agent-5.1.2-1.cm512.p0.116.el6.x86_64.rpm  cloudera-manager-daemons.

Re: Error: JAVA_HOME is not set and Java could not be found

Ok so at this point I need to clarify, there is no valid reason to install the openJDK, generally speaking we only support the oracle JDK.

 

IMHO there is something that has taken place up to this point that is preventing proper installation, perhaps things failed initially as the VM you are using failed to finish critical DB setup steps due to not having enough memory.

 

IMHO really starting over with a fresh CentOS 6.4 or 6.5 VM makes sense at this point.

 

Once that VM is created make sure you have followed the "requirements" section of our installation guide with regard to the proper configuraiton of networking on your VM, I suggest setting up bridged networking in your VM software.

 

http://www.cloudera.com/content/cloudera/en/documentation/cloudera-manager/v5-latest/Cloudera-Manage...

 

Then download the simple installler and follow the path A installation steps, using the embedded postgres DB. 

This is detailed here in the section titled "

Download and Run the Cloudera Manager Server Installer"

You will then use CM to configure you "other" host, once its started...  dont pre-install any packages on it.

Thank you very much! I'll reinstall it again.

Highlighted

I sucessfully reinstalled it by 'Installation Path A - Automated Installation by Cloudera Manager' after increase memory to 4GB.

thank you very much!

Hi,

 

I've been having the same issue but everything is working properly at my client cluster.

 

The only thing that I'd like to clarify is that echo $JAVA_HOME command returns empty line and the client is asking my why.

 

And what get me courious about it is that on Cloudera Manager, the Java Home Directory is empt as well.

 

java -version

java version "1.7.0_45"

 

rpm -qa | grep oracle

oracle-j2sdk1.7-1.7.0+update67-1.x86_64

 

ps auxf  | grep java

/usr/java/jdk1.7.0_67-cloudera/bin/java

 

At this point I understand that there are 2 java versions installed and the whole system is using jdk1.7.0_67-cloudera.

 

So what the heck java home directory on Cloudera Manager is empty? :)

 

Thank you

 

Fabricio

Re: Error: JAVA_HOME is not set and Java could not be found

Super Collaborator

JAVA_HOME does not need to be set in the shell for things to work (nor does linux alternatives have to point to the oracle JDK for default command line). 

 

JDK discovery is handled for the platform in /usr/share/cmf/bin/cmf-server

 

It can be set for CM in the /etc/default/cloudera-scm-server file if needed, but also within the CM UI for CDH if the JDK is in a custom location

Hi,

Thank you for your reply.

Now everything makes sense to me.

Best

Re: Error: JAVA_HOME is not set and Java could not be found

If you choose to use a custom Java location, modify the host configuration to ensure the JDK can be found:
Open the Cloudera Manager Admin Console.
In the main navigation bar, click the Hosts tab and optionally click a specific host link.
Click the Configuration tab.
Select Category > Advanced.
Set the Java Home Directory property to the custom location.
Click Save Changes.
