All,  
I am having some issue with getting file input and avro codec to work together.  
The idea is to read an avro file into a json object and then insert it into Elasticsearch.

Below is my config file.  
input {  
file {  
path =\> "C:/dev/testData/xxx/weather.avro"  
start\_position =\> "beginning"  
codec =\> avro {  
schema\_uri =\> "C:/dev/testData/xxx/weather.avsc"  
}

```
sincedb_path=>"C:/dev/testData/property/db"

```

}  
}

output {

```
stdout { codec => rubydebug }

```

}

Here is the log:

2018-10-18T13:45:09,523][DEBUG][filewatch.tailmode.handlers.grow] read\_to\_eof: get chunk  
[2018-10-18T13:45:09,599][DEBUG][logstash.inputs.file] Received line {:path=\>"C:/dev/testData/chewer/weather.avro", :text=\>"Obj\x01\x04\x14avro.codec\bnull\x16avro.schema\xF2\x02{"type":"record","name":"Weather","namespace":"test","fields":[{"name":"station","type":"string"},{"name":"time","type":"long"},{"name":"temp","type":"int"}],"doc":"A weather reading."}\x00\xB0\x81\xB3\xC4"}

The test files are from Avro's own repo (weather.avro)

I use avro 1.8.2 and logstash-codec-avro-3.2.3-java.  
Please advise.
