Question about connecting to HBase

Jerry <boyeggp...@...>

Hi ,

Sorry for the repost!

I am new to the JanusGraph and setup a JanusGraph database on my cluster .The storage is HBase with Zookeeper as coordinator.

I try to run the GraphOfTheGodsFactory example from IntelliJ Idea. I configure the janusgraph-hbase.properties as following:

storage.hostname=10.1.1.2,10.1.1.3,10.1.1.4

storage.port=2181

The IP addresses are zookeeper servers.

I run the following codes:

JanusGraph g = JanusGraphFactory.open("/janusgraph/conf/janusgraph-hbase.properties");
load(g);

I get the following error message:

java.lang.ClassNotFoundException: org.apache.hadoop.hbase.MasterNotRunningException

at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)

at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

but I can connect to the Hbase in gremlin shell with the same conf file.

I know the error message is about the ClassNotFoundException but it seems the JanusGraphFactory cannot connect to Hbase and then reports the MasterNotRunningException after checking the source code

public final static <T> T instantiate(String clazzname, Object[] constructorArgs, Class[] classes) {
    Preconditions.checkArgument(constructorArgs!=null && classes!=null);
    Preconditions.checkArgument(constructorArgs.length==classes.length);
    try {
        Class clazz = Class.forName(clazzname);
        Constructor constructor = clazz.getConstructor(classes);
        T instance = (T) constructor.newInstance(constructorArgs);
        return instance;
    } catch (ClassNotFoundException e) {
        throw new IllegalArgumentException("Could not find implementation class: " + clazzname, e);
    } catch (NoSuchMethodException e) {
        throw new IllegalArgumentException("Implementation class does not have required constructor: " + clazzname, e);
    } catch (InstantiationException e) {
        throw new IllegalArgumentException("Could not instantiate implementation: " + clazzname, e);
    } catch (IllegalAccessException e) {
        throw new IllegalArgumentException("Could not instantiate implementation: " + clazzname, e);
    } catch (InvocationTargetException e) {
        throw new IllegalArgumentException("Could not instantiate implementation: " + clazzname, e);
    } catch (ClassCastException e) {
        throw new IllegalArgumentException("Could not instantiate implementation: " + clazzname, e);
    }
}

I wonder if you have any suggestion on solving this problem?

Thanks in advance!

Hi Jerry,

What does your load() function/method look like?

Did you include the janusgraph-hbase dependency in your Intellij project?

Cheers, Marc

Hi Marc，

I use the GraphOfTheGodsFactory example and the load method is exactly same as the source code.

The following is the code snippet and the link to github :https://github.com/JanusGraph/janusgraph/blob/master/janusgraph-core/src/main/java/org/janusgraph/example/GraphOfTheGodsFactory.java

public static void loadWithoutMixedIndex(final JanusGraph graph, boolean uniqueNameCompositeIndex) {

load(graph, null, uniqueNameCompositeIndex);

}

public static void load(final JanusGraph graph) {

load(graph, INDEX_NAME, true);

}

public static void load(final JanusGraph graph, String mixedIndexName, boolean uniqueNameCompositeIndex) {

Based on the error message, it seems the program stopped at open() function before the load():

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/MasterNotRunningException

Hi Marc,

I manually add the hbase dependency

janusgraph-hbase-core-0.2.0-SNAPSHOT.jar

into the project.

Hi Jerry,

You need janusgraph:janusgraph-hbase:0.2.0-SNAPSHOT (or maybe better, if you did not change anything in JanusGraph, janusgraph:janusgraph-hbase:0.1.0 which is downloaded from maven central)

Cheers, Marc
