the problem is like the topic. I'm not sure if I misunderstood something or
I missed some configurations. The ES works fine in usual situations, but
doesn't work with rexster gremlin extension.
In java, I configured the graph as follows:
https://lh3.googleusercontent.com/-kd6vKDQdH6g/U7RbYPE-ciI/AAAAAAAAAHk/sSU5e5R3DMM/s1600/1.PNG
https://lh3.googleusercontent.com/-9HiEPJmS1FQ/U7Rbjmg4oCI/AAAAAAAAAHs/2FgdAtjiBHc/s1600/2.PNG
In the extension, I wrote:
*String query = "v." + propKey + ": (" + propValue + ")"; *
if(((TitanGraph) graph).indexQuery("search",
query).vertices().iterator().hasNext()){...}
When I invoked the extension, the rexster told: null pointer exception,
unknown index, etc. As follows:
https://lh4.googleusercontent.com/-I0w-hVgu0F0/U7RdQCcjOZI/AAAAAAAAAH4/4l13192eR2k/s1600/3.PNG
https://lh3.googleusercontent.com/-phHCRqzQN6I/U7RdUkyE8oI/AAAAAAAAAIA/rhkTlffd8lI/s1600/4.PNG
After this, I searched some advices from google and made some
configurations in rexster.xml

Then, the problems seemed as another way. (As you can see, first_example is
the name of the graph.)

Besides, when I invoked the extension, I've been told: the graph is
non-configured.

I've also tried the embedded mode. The problems seem to be the same.
Plus, I'm using:
Titan 0.4.2
Tinkerpop 0.2.4
Cassandra 2.0.7
ElasticSearch 1.2.1
This problem's driving me crazy. Any pointer would be appreciated! Thanks
in advance!
