Hi all,  
I try to use this config below to start logstash:

```
input {
  snmp {
    hosts => [{host => "udp:192.27.18.351/5000" version => "3"}]
    security_name => "admin"
    auth_protocol => "sha2"
    auth_pass => "Local_1234"
    priv_protocol => "aes"
    priv_pass => "Localme_1234"
    security_level => "authPriv"
    get => ["1.3.6"]
  }
}

```

However it returns error when start:

```
[2019-12-02T00:20:06,379][ERROR][logstash.pipeline] Error registering plugin {:pipeline_id=>"main", :plugin=>"<LogStash::Inputs::Snmp auth_protocol=>\"sha2\"...
:error=>"uninitialized constant Java::OrgSnmp4jSecurity::AuthSHA2::ID"
Failed to execute action {:id=>:main, :action_type=>LogStash::ConvergeResult::FailedAction, :message=>"Could not execute action: PipelineAction::Create<main>, action_result: false", :backtrace=>nil}

[2019-12-02T00:20:12,383][INFO][logstash.runner] Logstash shut down.

```

Anyone can help me on setup Logstash with snmp version 3?  
Actually, I have Huawei server(A) which was config to public data through snmp v3 to another server (B). I would like to use snmp trap with logstash on server B to collect data, however it seems no snmp v3 configuration for snmp trap plugin.
