Has anyone been successful in grabbing tokenized fields from ES to go in to Mahouts format? You can point to an index using $MAHOUT\_HOME/bin/mahout lucene.vector but the possibility to have multiple indexes is pretty high in ES so what is the best strategy for doing this? Can anyone give me a good starting point to go from? Thanks, Adam ---

Hi Adam, Just curious, did you find a working approach for this?

I have not but I assume (after watching one of Shay's videos) that the main index or (0) is where the data I need is located.

Hi, 2011/8/24 Adam Estrada [estrada.adam@gmail.com](mailto:estrada.adam@gmail.com): > I have not but I assume (after watching one of Shay's videos) that the > main index or (0) is where the data I need is located. if you don't want to deal with multiple indices (multiple index shards) you can set number of shards to 1 with curl -XPUT '[http://localhost:9200/mahout\_index/](http://localhost:9200/mahout_index/)' -d ' index : number\_of\_shards : 1 number\_of\_replicas : 1 ' With the default settings you will find Lucene index which you can open with Luke, Mahout etc. in ES/data/elasticsearch/nodes/0/indices/mahout\_index/0/index If you do need multiple indices (multiple index shards), with shared FS gateway defined you can open all indices in shared gateway location (one by one and create Mahout vectors from each). Hope this helps, Tomislav > Adam > > On Aug 23, 12:31 pm, AGuereca [aguer...@gmail.com](mailto:aguer...@gmail.com) wrote: > > > Hi Adam, > > > > Just curious, did you find a working approach for this? > > > > Thanks, > > ~AG > > > > On Aug 18, 1:04 pm, Adam Estrada [estrada.a...@gmail.com](mailto:estrada.a...@gmail.com) wrote: > > > > > Has anyone been successful in grabbing tokenized fields from ES to go > > > in to Mahouts format? > > > > > You can point to an index using $MAHOUT\_HOME/bin/mahoutlucene.vector > > > but the possibility to have multiple indexes is pretty high in ES so > > > what is the best strategy for doing this?
