Not that I'm aware of. 2010/2/25 Tim Terlegård tim.terleg...@gmail.com 2010/2/25 Bradford Stephens bradfordsteph...@gmail.com: Thanks for coming, everyone! We had around 25 people. A *huge* success, for Seattle. And a big thanks to 10gen for sending Richard. Can't wait to see you all next month. Did anyone record the event? /Tim

You can find a map here: http://www.washington.edu/home/maps/southcentral.html?cse Last month, we had a great talk from Steve McPherson of Razorfish on their usage of Hadoop. This month, we'll have Richard Kreuter from MongoDB talking about, well, MongoDB. As well as assorted discussion on the Hadoop ecosystem. If you can, please RSVP here (not required, but very nice): http://www.meetup.com/Seattle-Hadoop-HBase-NoSQL-Meetup/ My cell # is 904-415-3009 if you have questions/get lost.

Re: Seattle / PNW Hadoop/Lucene/HBase Meetup, Wed Sep 30th
Hey PNW Clouders! I'd really like to chat further with the crew doing distributed Solr.

If no one offers, We'll then have discussion and 'social time'. we'll just have general discussion. Let net know if you're interested in speaking or attending. We'd like to focus on education, so every presentation *needs* to ask some questions at the end. We can talk about these after the presentations, and I'll record what we've learned in a wiki and share that with the rest of us.

Re: Sharded Index Creation Magic?
I do, but you raise an interesting point. I had named the field incorrectly. I'm a little puzzled as to why individual search worked with the broken field name, but now all is well!

Sharded Index Creation Magic?
Hello! I'm working with Solr-1.3.0 using a sharded index for distributed, aggregated search. I've successfully run through the example described in the DistributedSearch wiki page. I have built an index from a corpus of some 50mil documents in an HBase table and created 7 shards using the org.apache.hadoop.hbase.mapred.BuildTableIndex. I can deploy any one of these shards to a single Solr instance and happily search the index after tweaking the schema appropriately. However, when I search across all deployed shards using the shards= query parameter ( http://host00:8080/solr/select?shards=host00:8080/solr,host01:8080/solrq=body\%3A%3Aterm), I get a NullPointerException: java.lang.NullPointerException at org.apache.solr.handler.component.QueryComponent.mergeIds(QueryComponent.java:421) at org.apache.solr.handler.component.QueryComponent.handleResponses(QueryComponent.java:265) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:264) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1204) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:303) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:232) Debugging into the QueryComponent.mergeIds() method reveals the instance sreq.responses (line 356) contains one response for each shard specified, each with the number of results received by the independant queries.
