[jira] [Commented] (NUTCH-2565) MergeDB incorrectly handles unfetched CrawlDatums

["Jurian Broertjes (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUTCH-2565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16509573#comment-16509573 ] 

Jurian Broertjes commented on NUTCH-2565:
-----------------------------------------

One solution would be to sum the retries of both CrawlDatums. We could do this only for db_unfetched or for others aswell. What do you think would be appropriate?

> I ran into this issue when merging a crawlDB originating from sitemaps into our normal crawlDB. CrawlDatums are merged based on output of AbstractFetchSchedule::calculateLastFetchTime(). When CrawlDatums are unfetched, this can overwrite fetchTime or other stuff.
> I assume this is a bug and have a simple fix for it that checks if CrawlDatum has status db_unfetched.
