-

i have elk installed on vm in laptop.elasticsearch , running.

./bin/logstash -f logstash-filter.conf gives me below error not find executable java binary. please install java in path or set java_home.

i tried setting java_home , $ path, still issue persistent. missing something?

 java /usr/bin/java   java -version java version "1.7.0_79" openjdk runtime environment (icedtea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2) openjdk 64-bit server vm (build 24.79-b02, mixed mode)  echo $java_home /usr/local/java/jdk1.8.0_45  echo $path /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/divija/bin:/usr/local/java/jdk1.8.0_45/bin

logstash-filter.conf

input { stdin { } }  filter {   grok {     match => { "message" => "%{combinedapachelog}" }   }   date {     match => [ "timestamp" , "dd/mmm/yyyy:hh:mm:ss z" ]   } }  output {   elasticsearch { host => localhost      index=>"myindex" }   stdout { codec => rubydebug }`enter code here` }

i had

export javacmd=`which java`

to make work.
