With the given explanation, I understand it as the following: You can use hadoop and do some map-reduce-jobs per csv-file. At the reducer-side, the reducer has to look for the id of the current doc and needs to create a hash of it. Now it looks inside a SortedSet, picks the next-best server and looks in a map, whether this server has got free capacity or not. That's cool. But it doesn't solve the problem at all, correct me if I am wrong, but: If you add a new server, let's call him IP3-1, and IP3-1 is nearer to the current ressource X, than doc x will be indexed at IP3-1 - even if IP2-1 holds the older version. Am I right? Thank you for sharing the paper. I will have a look for more like this. > In this case the lack of good docs and user-level API can be blamed on > the fact that this functionality is still under heavy development. > I do not only mean documentation at the user-level but also inside a class, if there is going on some complicated stuff. - Mitch -- View this message in context: http://lucene.472066.n3.nabble.com/anyone-use-hadoop-solr-tp485333p1426728.html Sent from the Solr - User mailing list archive at Nabble.com.
