------------------------------------------------------------------------------
Key: NUTCH-323
URL: http://issues.apache.org/jira/browse/NUTCH-323
Project: Nutch
Issue Type: Bug
Affects Versions: 0.8-dev
Reporter: Stefan Groschupf
Priority: Critical
Fix For: 0.8-dev
Using CrawlDatum.set(aOtherCrawlDatum) copies the data from one CrawlDatum to a
other.
Also a reference of the MapWritable is passed. Means both project share the
same mapWritable and its content.
This causes problems with concurent manipulate mapWritables and its key-value
tuples.
