make neo4j can't started #20

Closed Donghuanyu closed 8 years ago

Donghuanyu commented 8 years ago

hello,I did what you said: 1.Clone this repository and run mvn install -DskipTests 2.Copy the jar files in target/dependency to your Neo4j instance's plugins folder 3.Also copy target/neo4j-elasticsearch-2.3-SNAPSHOT.jar to the plugins folder 4.Modify conf/neo4j.conf accordingly like this: elasticsearch.host_name=http://localhost:9200 elasticsearch.index_spec=actor:Actor(name), director:Director(name), movie:Movie(title),person:Person(name), user:User(name) 5.Restart Neo4j

and I'm sure the elasticsearch service run in the localhost:9200 but,when I restart Neo4j,it can't start,there are error on starting:

I am having the same issue.

Donghuanyu commented 8 years ago

@az-ericso hi,are you have already solve this problem?if you have,can you help me?

Donghuanyu commented 8 years ago

I solved this problem.this is the version cause this problem.I use NEO4J 3.0.1,so I change the NEO4J's version 2.0.3 to 3.0.1 in the program.and there are some change in code at ElasticSearchKernelExtensionFactory.java. like this:

`@Description("Settings for the Elastic Search Extension")
    public static abstract class ElasticSearchSettings {
        public static Setting<String> hostName = Settings.setting("elasticsearch.host_name", Settings.STRING, (String) null);
        public static Setting<String> indexSpec = Settings.setting("elasticsearch.index_spec", Settings.STRING, (String) null);
        public static Setting<Boolean> includeIDField = Settings.setting("elasticsearch.include_id_field", Settings.BOOLEAN, "true");
        public static Setting<Boolean> includeLabelsField = Settings.setting("elasticsearch.include_labels_field", Settings.BOOLEAN,
                "true");
        // todo settings for label, property, indexName
    }
@Override
    public Lifecycle newInstance(KernelContext arg0, Dependencies dependencies) throws Throwable {

        Config config = dependencies.getConfig();

        return new ElasticSearchExtension(dependencies.getGraphDatabaseService(),
                config.get(ElasticSearchSettings.hostName), config.get(ElasticSearchSettings.indexSpec),
                config.get(ElasticSearchSettings.includeIDField), config.get(ElasticSearchSettings.includeLabelsField));
    }`

then build,and do what readme.adoc said. I hope it can help you. @az-ericso

az-ericso commented 8 years ago

Thanks @Donghuanyu. It works for me as well.

jexp commented 8 years ago

Good that it works for you, I tried to update to Neo4j 3.0.1 but I consistently get ES connection errors :( which I can't resolve. With ES 2.3.2

jexp commented 8 years ago

Can you try this branch (if it works for you) and report back: https://github.com/neo4j-contrib/neo4j-elasticsearch/tree/3.0

az-ericso commented 8 years ago

Actually, it still does not work. I have no idea why the neo4j was running. I am getting the same error using this error:

can we reopen this issue?

Did you see this error? ElasticSearch Integration: syntax error in index_spec

what does your index-config look like in neo4j.conf ?

jexp commented 8 years ago

Did you clean out your plugins directory before trying again? Otherwise you might have old files in there.

I updated the instructions for building it: mvn clean install -DskipTests

Which ES version are you using? I have troubles with the integration test.

Does the test work for you?

az-ericso commented 8 years ago

I am using AWS elasticSearch service. The configuration settings is neo4j.conf.

It seems it cannot read the configuration. :(

az-ericso commented 8 years ago

@jexp sorry that I was looking at the wrong directory. In AWS, the configuration is in /etc/neo4j/neo4j.conf instead of /var/lib/neo4j/conf/neo4j.conf.

I used the following command to find out. I hope this can help other people:

dpkg -L neo4j
az-ericso commented 8 years ago

No error in the log anymore. But nothing is stored inside elasticSearch :(

jexp commented 8 years ago

I tested it and it worked for me, what does your index-spec look like? and what kind of data did you create in Neo4j?

4ossiblellc commented 8 years ago

Thanks for your quick response. I have a label named "Tech" with a field named "keyword" having words separated by "space" in a string format.

The configuration is:

elasticsearch.index_spec=tech:Tech(keyword)

I put this configuration in both neo4j.conf and neo4j.properties (based on the neo4j website)

Sorry that I have another github account. I am also @az-ericso.

jexp commented 8 years ago

Did you configure the host?

What do the nodes that you create look like?
