Hi Markus, a closing bracket is missing/not in place, see {{NUTCH-1646-2.patch}}. Also counter "Perm redirects deleted" could be removed: it's name is wrong because temporary redirects are included and we do not really need a second counter in addition to "Deleted redirects" (except for backward-compatibility).

> IndexerMapReduce does not remove gone and redirects via DB status, only fetch status. This means segments merged before we fixed SegmentMerger may contain records that do not have a correct status. For example, some pages are gone on the web, gone in the CrawlDB, gone in the segments. But merging those old segments could cause a older status to prevail, causing it to be indexed although the CrawlDB says it's gone.
