Mmmm OK @okedoki we need to resolve this conflict. The issue here is that
you have indented everything by 4 spaces by the looks of it. This is incorrect
as indenting accoridng to the code formatting template is 2 space indents.
Please update the ppull request again if you could. Thanks

> Citing Sebastian at NUTCH-2420:
> ??The correct solution would be to use <host,score> pairs as keys in the
> Selector job, with a partitioner and secondary sorting so that all keys with
> same host end up in the same call of the reducer. If values can also hold a
> HostDb entry and the sort comparator guarantees that the HostDb entry
> (entries if partitioned by domain or IP) comes in front of all CrawlDb
> entries. But that would be a substantial improvement...??
