I'm using Flume's HDFS SequenceFile sink for writing data to HDFS.
I'm looking for a possibility to create "custom keys". Per default, Flume is using the Timestamp as key within a SequenceFile. However, in my usecase I would like to use a customized string as key (instead of the timestamp).
What are best practices for implementing/configuring such a "custom key" within Flume?
