Debugging Map Reduce Jobs at Solr

[Furkan KAMACI <fu...@gmail.com>]

Is there any easy way(tools etc.) that I can debug Map Reduce jobs of Solr?

Hi,

Please elaborate your question. Solr does not have any M/R jobs, so you have to let us know your setup.

Was suspecting that you are referring to the Map/Reduce used by Nutch2
(please note that 1.6 does not use Map/Reduce). As far as I know,Nutch2
uses Map/Reduce for distributed crawling, and only uses Solr for indexing
the collected data.

If you need to understand Map/Reduce for Nutch2, have you checked the
documentation, e.g.,
http://wiki.apache.org/nutch/Nutch2Tutorial
http://wiki.apache.org/nutch/NutchHadoopTutorial

Ok, thanks for your responses. Actually I was wondering about indexing and
reindexing from nutch to Solr and debugging them. I think according to your
responses there is no difference for Solr side that data is coming through
a map reduce or not.

Hi,

Solr doesn't really do MapReduce jobs.  Maybe you mean distributed
search where queries are dispatched to N servers and then responses
are merged/reduced to top N and returned?
