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
