Would this be useful in metron-common? Doesn't have to be this PR, but
maybe "LoadOptions" becomes a parameterized type OPT_TYPE.
> Unify and Improve the Flat File Loader
> --------------------------------------
>
> Key: METRON-682
> URL: https://issues.apache.org/jira/browse/METRON-682
> Project: Metron
> Issue Type: Improvement
> Reporter: Casey Stella
>
> Currently the flat file loader is deficient in a couple ways:
> * It only supports importing local data despite there being a separate,
> poorly named, application which supports importing enrichment via MapReduce
> called threat_intel_loader.sh
> * It does not support local imports from HDFS
> * It does not support local imports from URLs
> * It does not support importing zipped archives locally
> * You cannot import more than one file at once
> This JIRA will:
> * Unify the MapReduce and local imports into one program and allow the user
> to specify the import mode with a CLI flag
> * Support local imports from HDFS and URLs
> * Support local imports from zipped files
> * Support importing more than one file at once
