>          Components: metadata
>    Affects Versions: 1.13
>            Reporter: Semyon Semyonov

> The class metadata/Nutch.java  public static final String ARG_SEGMENT = "segment" is not used correctly. In some cases Fetcher and ParseSegment it is interpreted as a single segmenet, in others CrawlDb, LinkDb, IndexingJob as an array of segments. Such misunderstanding leads to inconsistency of usage of the parameter.
> After a discussion with [~wastl-nagel]  the proposed solution is to allow the usage of both array and a string in all cases. That gives an opportunity to not introduce the broken changes.
> A path is proposed.
>  *The question left is refactoring, all these five components share the same code(two versions of the same code to be precise). Shouldn't we extract a method and reduce duplicates?  *
