> Reporter: Steve Blackmon
> Assignee: Steve Blackmon
>
> Currently streams-persist-hdfs writer creates (and reader expects) exactly four columns. this could be made much more flexible without too much effort.
> Update reader to support additional use cases:
> a) file paths containing one json document per line
> b) file paths containing just id and json on each line,
> c) file paths containing id timestamp and json document on each line
> Update writer support
> a) ids only
> b) ids and timestamp only
> c) ids timestamp and json only
