Hello, i have a newbie question.  
I think i have the correct java version, however, i got the following error from running logstash. any pointer is appreciated!  
echo $JAVA\_HOME  
/export/apps/jdk/JDK-1\_8\_0\_5  
After I updated $JAVA\_HOME to 1\_8\_0\_72, i have the same problem.  
$ java -version  
java version "1.8.0\_72"  
btw, i installed logstash using "yum install"..

$ sudo bin/logstash –f /etc/logstash/conf.d/filebeattofile.conf --config.reload.automatic

BTW, i resolved this issue by downloading tarball version instead of the rpm version.  
thanks for your attention.
