cloudera manager will not start - fresh install

[#1]

Hello,

I have completed installation of Cloudera Enterprise 5.6.x on Red Hat Enterprise Linux Server release 6.7 in steps described as "installation path b" without errors.

http://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_install_path_b.html#cmig_topic_...

Start of cloudera manager immediately fails - cloudera-scm-server.out only contains a few lines..

cd /var/log/cloudera-scm-server/
[hduser@slrs01va6f1clm1 cloudera-scm-server]$ cat *.out

JAVA_HOME=/usr/java/jdk1.8.0_72
/usr/share/cmf/bin/cmf-server: line 129: /usr/java/jdk1.8.0_72/bin/java: Permission denied
/usr/share/cmf/bin/cmf-server: line 129: exec: /usr/java/jdk1.8.0_72/bin/java: cannot execute: Permission denied

Java JDK was installed as described here:

http://www.cloudera.com/documentation/enterprise/latest/topics/cdh_ig_jdk_installation.html?scroll=t...

Java environment for "hduser"..

echo $JAVA_HOME
/usr/java/jdk1.8.0_72

[hduser@slrs01va6f1clm1 cloudera-scm-server]$ java -version
java version "1.8.0_72"

Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)

I would appreciate any suggestions on how to proceed.

Thank you

Looking back at your permissions, it appears that you have the following as reported by "stat /usr/java/jdk1.8.0_72/bin/java":

Access: (0776/-rwxrwxrw-) Uid: ( 504/ hduser) Gid: ( 504/ hadoop)

Since the shell used to start Clouder Manager is owned by cloudera-scm, this would mean that unless you altered your init script to start as user "hduser" then "other" users don't have access to run java.

Try adding the execute permission for other on your java binary and try starting Cloudera Manager.

Regards,

Ben

Thanks for the quick response. You're suggestion allowed to inch closer, but new problem exists..

[hduser@slrs01va6f1clm1 ~]$ sudo sudo service cloudera-scm-server start
[sudo] password for hduser:

[hduser@slrs01va6f1clm1 ~]$ cd /var/log/cloudera-scm-server/

I created symlink for java and ensured shared library is recognized for access by root user..

[hduser@slrs01va6f1clm1 cloudera-scm-server]$ cd /usr/bin
[hduser@slrs01va6f1clm1 bin]$ ls -l java

[hduser@slrs01va6f1clm1 bin]$ echo $LD_LIBRARY_PATH

Any suggestions?

Much appreciated.

Thanks!

It appears that cloudera-scm still cannot access files in the java directories.  Check that the file is read/execute by other.

This is mine:

-rwxr-xr-x 1 root root 106366 Sep 2 2014 libjli.so

I recommend just doing the following as again it appears there are permission problems in your JDK

chmod -R 777 /usr/java/jdk1.8.0_72

I'm not sure why permissions are like they are, but normally java is accessible by "other" I believe.

Regards,

Ben

[#5 · Accepted solution]

Suggested chmod applied, but problem persisted.

Solution was to re-install with 5.5.2.

Thanks for your replies.

It looks like you installed Java as hduser instead of as root. This will prevent other users from accessing it.

Could you try uninstalling java, and re-installing it as root?

I got the same problem when I put the Java files in my home directory. It only worked after I put the Java files in the /usr/java directory.
