How to using Hadoop under the Solr ?

[Trọng Trần Bình <tr...@asnet.com.vn>]

Hi all,
I have Index repository by Lucene in Hadoop, I am using Solr for web search
interface. How can I using those indexed repositories with Solr web search?

I agree with Tim.

There is on-going work to support building SOLR index using MapReduce.
See http://issues.apache.org/jira/browse/SOLR-1045. The initial patch
does what Tim described - build Lucene indexes the same way that SOLR
would do. Later patches would be different as it will use the new
mapreduce package when it comes out in 0.20.

Cheers,
Ning

Solr - Hbase, sounds interesting, coz i'm currently develop an google
books like application.

If there is any url that i can read, it would be great ..

I am definitely not an expert in SOLR, and I would like to be
corrected, but to my knowledge unless you have built the Lucene
indexes the same way that SOLR would do so (handling types etc the
same way) then you won't be able to use SOLR search with the indexes
built.

Assuming they are the same - once you have built the indexes, I think
you then need to copy them out of HDFS into a vanilla SOLR
installation - e.g. it has nothing to do with hadoop anymore.

If your indexes are very large, you might consider Katta to search
across them.  I don't think this plays well with SOLR though.

I am also interested in using with SOLR  indexes built from HBase so I
am interested in your findings.

Cheers,

Tim
