> After NUTCH-506, if you run parse on a segment, parseData's contentMeta
> accumulates metadata of every content parsed so far. This is because
> NUTCH-506 changed constructor to create a new metadata (before NUTCH-506, a
> new metadata was created for every call to readFields). It seems hadoop
> somehow caches Content instance so each new call to Content.readFields during
> ParseSegment increases size of metadata. Because of this, one can end up with
> *huge* parse_data directory (something like 10 times larger than content
> directory)
