I want to read a avro files from kafka topics and insert into elastic search.  
when I am reading avro files and showing results(codec=\>json) ,it gives empty.  
below is my configuration:

```
input
{
kafka {
bootstrap_servers =>"servers"
topics => ["topic"]
group_id => "group id"
auto_offset_reset => "latest"

    codec => avro {
        schema_uri => "/app/kn00/logstash-7.0.0/schemas/abc/abc_schema_writer.avsc"
    }

jaas_path => "/app/logstash-7.0.0/zookeeper-jaas_tmx.conf"
sasl_kerberos_service_name => "kafka"
kerberos_config => "/app/logstash-7.0.0/krb5.conf"
#sasl_mechanism => "PLAIN"
security_protocol => "SASL_SSL"
ssl_truststore_location => "/app/kafka-security.jks"
ssl_truststore_password => ""
}
}

output {

stdout{ codec => json }

    elasticsearch {
      hosts => ['url']
       user => 'abcedf'
       password => ''
       ssl => true
       truststore => "/app/kafka-security.jks"
      truststore_password => ""
       index => "dev_abc_error"
      # document_id => ""
       document_type => "_doc"
 }}

```

and the output is like below:  
/app/logstash-7.0.0/vendor/bundle/jruby/2.5.0/gems/awesome\_print-1.7.0/lib/awesome\_print/formatters/base\_formatter.rb:31: warning: constant ::Fixnum is deprecated  
{  
"name" =\> "",  
"value" =\> "",  
"@version" =\> "1",  
"@timestamp" =\> 2019-06-03T17:19:31.204Z  
}  
{  
"name" =\> "",  
"value" =\> "",  
"@version" =\> "1",  
"@timestamp" =\> 2019-06-03T17:19:31.221Z  
}

I am able to read the same avro records using NiFi and able to index into elastic search.

thanks for reading and helping
