Hi all,  
been battling with this all day. Ultimately I'm suffering from  
NoClassDefFoundError for BulkRequestLoader. When I look in the jar  
I can't find it.

Here's how I get to the problem:

Install couchdb-river:

> bin/plugin -install elasticsearch/elasticsearch-river-couchdb/1.1.0

Start elasticsearch:

> bin/elasticsearch -f

Responds with:  
[2012-02-28 11:00:17,933][INFO][node] [Leir]  
{0.18.7}[1508]: initializing ...  
[2012-02-28 11:00:17,948][INFO][plugins] [Leir]  
loaded [river-couchdb], sites   
[2012-02-28 11:00:20,031][INFO][node] [Leir]  
{0.18.7}[1508]: initialized

Now for CouchDb.

I have initialisation file:  
{  
"type" : "couchdb",  
"couchdb" : {  
"host" : "localhost",  
"port" : 5984,  
"db" : "tracks",  
"filter" : null  
},  
"index" : {  
"index" : "tracks",  
"type" : "tracks",  
"bulk\_size" : "100",  
"bulk\_timeout" : "10ms"  
}  
}

I load it with:

> curl -T "{../init\_file}" -XPUT 'localhost:9200/\_river/tracks/\_meta'

But, I see elasticsearch respond with:  
[2012-02-28 11:00:46,213][INFO][cluster.metadata] [Leir]  
[\_river] creating index, cause [auto(index api)], shards [1]/[1],

Now, if I close/restart Elasticsearch I get the same exceptions thrown/  
reported.

Note: investigated further. BulkRequestLoader is in the source-repo,  
so I downloaded 0.19RC. The CouchDb river plugin works fine with  
this.

I'm now happily searching dozens of docs. Hooray.

I now realise the GitHub docs do clearly explain this (0.19 -\> 1.1.0,  
0.18 -\> 1.0.0)

My bad.
