Description

Using OnFileUnorderedPartitionedKVOutput there is no way of passing custom properties to its keySerializer class given that this class implements Configurable.

For OnFileSortedOutput this is possible because comparatorConf and partitionerConf touching both sides, the input and the output.

Possible solutions could be either passing a map to keySerializer configuration as well or have custom properties for the input and the output of an edge.
