Hello,
I'll try to evaluate elasticsearch as an alternative to sphinx search.
So, my first need is to replace quickly indexer provide by sphinx.
JDDB was the solution but I can't get it running at all.
It seems that I can't intall any rivers.
The process I'll try on both ubuntu precise 64 and debian squeeze 64 :
- Install SE 0.19.8 from deb package.
- The server is running very quickly and working
- Install a plugin head to interract with ES without using curl, the plugin
is running successful. - Install jdbc rivers plugins :
bin/plugin -install jprante/elasticsearch-river-jdbc
-> Installing jprante/elasticsearch-river-jdbc...

I'll try to a lot of time on different server but I can't have any other
message.
I'll try with wikipedia river just for try another river type the same
error Failed to load class
It drive me nuts since I really don't see where I failed (moreover just at
the begining).
I'll try to manually put some data on ES and all seems to work.
Any help will be greatly appreciate.
Thanks.
