Couchbase -> Elasticsearch tutorial fails

[Francis Varga]

I try on this page: http://www.couchbase.com/docs/couchbase-elasticsearch/couchbase-elastic-configurations.html

to execute: curl -XPUT http://localhost:9200/_template/couchbase \

-d @plugins/transport-couchbase/couchbase_template.json

But i get always an error:

{"error":"ElasticSearchParseException[Failed to derive xcontent from org.elasticsearch.common.bytes.ChannelBufferBytesReference@2346d0e8]","status":400}

Any suggestions for this?

Cheers

I have not seen this error before.  What version of Couchbase and Elasticsearch are you running?

Also, can you paste the full stack trace from Elasticsearch, that will up us identify what the plugin may be doing when this error occurs.

Thanks,

marty

I'm using the Mac Version of Couchbase + Elasticsearch Version: 0.90.3, Build: 5c38d60/2013-08-06T13:18:31Z, JVM: 1.7.0_25

what do you mean with "full stack trace"?

Cheers

We have not tested with 0.90.3 its possible there are more incompatibilities there.  Is it possible for you to try with 0.90.2?

Generally an error of the sort you described will be come with a full stack trace in the logs.  This has many lines of output showing the stack of the thread that encountered the exception.  Frequently this includes line numbers pointing to where the source of the problem is.

So the first question is where are you seeing this error?  In the Couchbase UI?  In a Couchbase log?  In the console where you started Elasticsearch?  In an Elasticsearch log file?

Directly in the terminal/console. When i'm executing the command.

I also get this error:

I am doing it from cbdocs bucket to cbdocs es index.

• 2013-11-12 18:02:22 [Vb Rep] Error replicating vbucket 63. Please see logs for details.

and my elastic search config (elasticsearch.yml) has:

couchbase.username: Administrator

couchbase.password: asdfasdf

couchbase.num_vbuckets: 64

couchbase.port: 9091

couchbase.defaultDocumentType: cbdoc

Ok that one I fixed by changing the XDCR protocol to Version 1 (it’s version 2 by default). But the whole template thing didn’t work but I am not familiar with what the template is needed for…

Ok to fix this issue… then you don’t have to curl -XPUT 

$ cd [path_to]/elasticsearch/config

$ mkdir templates

$ cd templates

$ cp [path_to]/plugins/transport-couchbase/couchbase_template.json .

restart elastic search

[Marty Schoch]

The error message reported here is curl telling the user that the file cannot be found.  The tutorial includes a step to change directory into the Elasticsearch installation directory, and its expected that all subsequent commands are executed from there.  If not, you'll have to adjust the paths accordingly.  If <elasticsearch>/plugins/transport-couchbase/couchbase_template.json doesn't exist, that would be a bug.

I'm not exactly sure what you mean by "you don’t have to curl -XPUT".  If you mean this step can be omitted, that is true, but you will not have the couchbase defaults installed.

You can alternatively just copy the JSON template file into elasticsearch/config/templates and on startup it will import it automatically...
