Looking at this right now

from gremlin-php.

Ah!
When the script runs , the CPU processing rises and takes about 1 minute to generate the error.

I am suspicious of anything of my environment , but the Rest API works, and the connection by Gremlin in the terminal too!

ok So... I can't seem to recreate this (at least not in a simple fashion).
I am using a vanilla titan-0.9.0-M2-hadoop1 downloaded from http://s3.thinkaurelius.com/downloads/titan/titan-0.9.0-M2-hadoop1.zip on ubuntu 14.04 LTS and I'm getting the expected result of [99]

Could you perhaps share your environment details? (os, java version, etc.) And possibly the Titan configuration files you are using if they're different from the default?

My project has a test.php file with the above code and a composer.json file with :

{
    "name": "root/testing",
    "require": {
        "brightzone/gremlin-php": "*"
    },
    "authors": [
        {
            "name": "Dylan Millikin",
            "email": "[email protected]"
        }
    ],
    "minimum-stability": "stable"
}

Also worth exploring: Could you run titan via bin/titan.sh -v start and see if any errors are thrown (either on gremlin-server startup or when gremlin-php queries the server)?

Thanks

Great thanks for the info. And just to make sure, the version of gremlin-php you're using is v1.0?
I'll recreate the above env and test.

rlacerda83 avatar rlacerda83 commented on August 16, 2024

Yes! v1.0

"name": "brightzone/gremlin-php",
        "version": "v1.0",
        "version_normalized": "1.0.0.0",
        "source": {

Hey!

Its works!

I shutdown the titan , updated ubuntu and updated java .

Started the titan and works!

A strange behavior that I saw was that time was about 5 processes Gremlin server running , I do not know if this is normal , and may have been the problem , why now only have one .

Thanks, and sorry for wasting your time.

PommeVerte avatar PommeVerte commented on August 16, 2024

Hey no problem.

I think I know what you mean. If you forget to stop titan via bin/titan.sh stop and start it again it will start another instance and everything goes crazy (I can't even seem to be able to stop titan without killing the processes manually).

I just wanted to give you a heads up about

338657 [gremlin-server-worker-1] WARN org.apache.tinkerpop.gremlin.server.handler.HttpGremlinEndpointHandler - Invalid request - responding with 400 Bad Request and no gremlin script supplied

As it is an odd error to get at all (400 isn't a valid error code as per the documentation) This might indicate an incorrect configuration. It might come from using HttpChannelizer instead of WebSocketChannelizer, though I'm not sure about this.

Anyways, glad it worked out. Let me know if you need any help with anything.
