error running elasticsearch Java Could not find any executable java binary

[outsourcedph]

I am unable to run elasticsearch when I run service elasticsearch start the ff below is what I did

[root@dc-lab05-06LVM ~]# export JAVA_HOME=/opt/jdk1.8.0_121/jre
[root@dc-lab05-06LVM ~]# echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/jdk1.8.0_121/bin/:/                                                        opt/jdk1.8.0_121/jre/bin:/root/bin
[root@dc-lab05-06LVM ~]# echo $JAVA_HOME
/opt/jdk1.8.0_121/jre
[root@dc-lab05-06LVM ~]# java -version

I also tried adding this on my /etc/profile

export JRE_HOME=/opt/jdk1.8.0_121/jre


[root@dc-lab05-06LVM ~]# $PATH
-bash: /usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin: No such file or directory

Set the path to executable Java env to the PATH variable or you can set it up directly in ES startup script

I tried it on Java, but it fails with the same error message, can you please point to to which line number exactly on ES startup script(what exactly is the filename - I just want to be sure, I am just a newbie on this arena). I appreciate your help.

I am still getting the same error even if I already changed to jdk1.8.0_131 rpm

Starting elasticsearch: which: no java in (/sbin:/usr/sbin:/bin:/usr/bin)

It fails also when I install the update alternatives
alternatives --install /usr/bin/jar jar /usr/java/jdk1.8.0_131/bin/jar 2
alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_131/bin/javac 2

That is an interesting article mate, I'll get to that once I get past this.
I am still getting this error when I run service elasticsearch, but when I issue it from /usr/share/elasticsearch/bin I can execute elasticsearch with no problem the nodes all start up

genuser@c0n0_12 elasticsearch]# service elasticsearch start
