Indexing does not work

[Nghi93]

Hi,

I am using Neo4j 3.0.7 and ElasticSearch 2.3.4 (both via Docker).

This is my neo4j.conf:

elasticsearch.host_name=http://elasticsearch:9200
elasticsearch.index_spec=people:Person(first_name,last_name), places:Place(name)

When creating a node create(n:Place { name: 'test' }) nothing happens in ES. How is the index supposed to be named? Also I don't get any log messages (neither in ES nor in Neo4j).

Could there be an incompatibility with this ES version?

[jexp]

can you check the neo4j logs for any error messages? in debug.log or neo4j.log did you put the jar into the plugins directory? can you remove the space after the comma in the config (I'm not sure if it likes that)

Also how did you change the neo4j config in the docker container? And how did you put the plugin into the docker container. Did you link the two containers?

[Nghi93]

Beside debug information in debug.log there were no error messages. Yes, I did put the jar files into the plugins directory:

commons-codec-1.9.jar   
gson-2.6.2.jar         
httpclient-4.5.2.jar    
jest-2.0.2.jar            
slf4j-api-1.7.13.jar
commons-lang3-3.3.2.jar 
guava-19.0.jar
httpcore-4.4.4.jar      
jest-common-2.0.2.jar
commons-logging-1.2.jar 
httpasyncclient-4.1.1.jar  
httpcore-nio-4.4.4.jar  
neo4j-elasticsearch-3.0-SNAPSHOT.jar

For the neo4j config in docker I have a local neo4j.conf file and I add it with ADD neo4j.conf conf/

For the plugins I have: COPY ./plugins/* plugins/

I am not that familiar with Docker, but I can curl neo4j from elasticsearch container and vice versa.

[santosh-hegde]

Compare jar files of plugins folder with jars of lib folder. If there are two same jars with different versions, then keep the higher versioned one. In case of 2 same jars with different versions also this issue will arise.

[jexp]

@Nghi93 did you work it out?

[ajaymodi]

@jexp @santosh-hegde @Nghi93 Can you guys help me? I followed all the steps as mentioned, I am using 3.1 branch and es version 2.4.4. I tried to create index but it does not create any index.

[santosh-hegde]

@Ajaymodi I'm not sure about ES 2.xx. Can you upgrade to 5.x and try once. If it didn't works, we can work on it.

[balajiforgithub]

@santosh-hegde: I am having the same issue with Neo4j 3.1.1 and ES 5.2. I have followed all the instructions that were defined. Could you please assist me on this.

[chiffa]

Same problem here: Neo4j 3.1.1 ES 5.2

I get the following error:

It seems the problem is with the plugin not finding the elasticsearch server, but when I look at the config file, I have:

elasticsearch.host_name=http://localhost:9200
elasticsearch.index_spec=people:Person(first_name, middle_name,last_name)

And when I check out the localhost:9200 in my browser I see

{
  "name" : "7OzSFpd",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "WsH-c2LSTnyAEZi9MGhUMA",
  "version" : {
    "number" : "5.2.2",
    "build_hash" : "f9d9b74",
    "build_date" : "2017-02-24T17:26:45.835Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

I am kinda out of ideas to what could have gone wrong here...

Update, the problem is now:

I released a new version, can you check with that again?

[chiffa]

Let me have a look at it when I have time

[18steps]

Have the same problem. I follow the guide. I'm using Neo4j CE 3.2.3 and ElasticSearch 5.6.0 on Windows 7.

As you can see, although it says the build is a success, the tests say "syntax error in index_spec" and " Running null - null"

When I do `curl "http://localhost:9200/_cat/indices?v" it reads

My %NEO_HOME%\conf\neo4j.conf file is

Did you use the same version as your neo4j instance has?

What does your spec look like in the config?
