Not sure how you are using the serializer but I understand it's part of an hdfs sink

When you do this:

your property goes to the sink.
To make it apperar in the serializer context it should be like this:


How are you using the serializer in the configuration?

Thanks for the reply Gonzalo. 

There is no configure method as Serializer doesn't extend Configurable. 
Do I have to extend Configurable to access custom configuration values?

P.S - Sent code sample and config in separate email directly to you.

Subject: Re: Context/Configuration values not passed to custom serializer.
It might be a bug in the sink you are using.
For instance, I have a serializer for the HbaseSink so I added two custom properties.


Then in the configure method the context has the properties "numberBuckets" and "customKey" (notice all the prefix of the property is removed and not passed to the serializer)
If you paste your configuration and code maybe we can spot where is your issue.

Hello All,

 I need to use some configuration values in my implementation of Serializer which extends only EventSerializer. 

For customizing behavior I am trying to use Context provided via Builder's build method. 

Although the configuration values or none of the Context properties are not passed to Serializer. 

I am able to use this Serializer without configuration through flume and write data so I am certain that my implementation works correctly. 

Any idea why Context is passed as empty to the Serializer?  Or any pointers on how I should go on debugging this issue?

Thanks for reading and appreciate your response.
