Failed to Start Appian18.3 Services on Linux

Hi All,

I am doing the fresh installation of Appian 18.3 on Linux machine. Did the basic changes but when executing a Service Manager script in the <APPIAN_HOME>/services/bin directory, the following error is returned:

 Exception thrown while attempting to retrieve process info for java process with main Class name QuorumPeerMain. java.io.IOException: Cannot run program "jps": error=2, No such file or directory
...
Caused by: java.io.IOException: error=2, No such file or directory

Followed the steps provided on “KB-1548 Cannot run program "jps" error when starting Service Manager”:

 It says that This error is returned when the JAVA_HOME path is set to JRE, rather than JDK. Please see below screenshot that java path is set to JDK.

I also opened the firewall port 2181, 2888, 3888, 9092, 7070 on linux machine but didn't helped.

Can anyone please help me on this.
