I am trying to setup HDFS encryption and need to use the included /usr/local/sbin/kms.sh script but it runs into several issues.  

1. First when running it:
# kms.sh

/usr/local/sbin/kms.sh
/usr/local/sbin/kms.sh: line 83: /usr/local/share/hadoop/kms/tomcat/bin/catalina.sh: Permission denied
/usr/local/sbin/kms.sh: line 83: exec: /usr/local/share/hadoop/kms/tomcat/bin/catalina.sh: cannot execute: Permission denied

I remedied this by running chmod +x /usr/local/share/hadoop/kms/tomcat/bin/catalina.sh 

2. When I run kms.sh I'm met by another error 
# kms.sh

The BASEDIR environment variable is not defined correctly
This environment variable is needed to run this program

I ran this to see what was happening in the script

# sh -x /usr/local/sbin/kms.sh 

and noticed that a script didn't exist 

...
+ exec /bin/catalina.sh
exec: /bin/catalina.sh: not found

I downloaded the catalina.sh script from a github repo - https://github.com/abridgett/pkg-hadoop/tree/master/share/hadoop/kms/tomcat/bin 

3. I ran it again
# sh -x /usr/local/sbin/kms.sh 

...
+ exec /bin/catalina.sh                                                                                                                                                                                            
Cannot find //bin/setclasspath.sh                                                                                                                                                                                  
This file is needed to run this program   

I add this file from the github page also

4. Final run

# kms.sh

kms.sh                                                                                                                                                                                
The BASEDIR environment variable is not defined correctly                                                                                                                                                          
This environment variable is needed to run this program 

At this point I don't know what to do to get this to run and running # sh -x /usr/local/sbin/kms.sh gives no more useful clues


# sh -x /usr/local/sbin/kms.sh

Note: Waiting for the process to end and use of the -force option require that $CATALINA_PID is defined
