I am trying to setup filebeat (6.2) with kafka output using lz4 compression, but always getting error as
ERR Invalid kafka configuration: kafka: invalid configuration (lz4 compression requires Version \>= V0\_10\_0\_0)
My output configuration is:
output.kafka:
hosts: ["kafka1:10092","kafka2:10092","kafka3:10092"]
topic: '%{[fields.log\_topic]}'
partition.round\_robin:
reachable\_only: false
required\_acks: 1
compression: lz4
max\_message\_bytes: 1000000
version: 0.11.0.0
Any insight on what might be wrong would be very helpful
Thanks.

Might be a bug. What happens if you set `version` to `0.10`?

Got the same error. Another surprising thing, possibly another bug, is that if I specify the version as
> version: 0.10
I got the error as
> Exiting: error initializing publisher: unknown/unsupported kafka version '0.1' accessing 'output.kafka' (source:'filebeat.yml')
specifying version as (with quotes)
> version: "0.10"
gives the original error
> Invalid kafka configuration: kafka: invalid configuration (lz4 compression requires Version \>= V0\_10\_0\_0)

This error is to be expected:
```auto
Exiting: error initializing publisher: unknown/unsupported kafka version '0.1' accessing 'output.kafka' (source:'filebeat.yml')
```
When using `1.10` without quotes, the YAML parser/spec will interpret the input as floating point value 🙂
With setting the version to `'0.10'`, you shouldn't get this error message. This is clearly a bug.
I see you've opened: [https://github.com/elastic/beats/issues/6414](https://github.com/elastic/beats/issues/6414)
Thanks!
