Connection refused when using hetio/py2neo to export to neo4j #11

Hi Daniel,

Do you remember what you needed to do to increase the number of concurrent open files allowable by neo4j? At the moment I get a warning that says:

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
Starting Neo4j Server...WARNING: not changing user
process [6305]... waiting for server to be ready..... OK.
http://localhost:7500/ is ready.

Also, I think they way that neo4j is started with a subprocess call in Python is giving me issues, since I trying to start neo4j 3.1.1 in the same manner causes the service to shut down immediately before any Python code can be executed.

dhimmel commented 7 years ago

So the warning is because your operating system is set to allow at most 1024 open files handles. However, it's just a warning... not an error. IIRC, the number of open files in Neo4j is only large if you have many users modifying the database at a given time. I don't think this should happen for our use cases... but if it does there will be an error message in the log.

It looks like in Neo4j 3.1, it's now easier to change the open file limit. But I suspect this isn't your problem.

I trying to start neo4j 3.1.1 in the same manner causes the service to shut down immediately before any Python code can be executed.

If we can get a log here that would be great!

The strange thing is that the neo4j.log file is empty when this happens. It seems that the server is starting, refusing a connection to the Python code, and then shuts down immediately.

neo4j-import.ipynb outputs something like:

Starting Neo4j.
WARNING: Max 1024 open files allowed, minimum of 40000 recommended. See the Neo4j manual.

My guess is that the following python line is actually shutting down the server:

    finally:
        subprocess.run([neo4j_bin, 'stop'])

This is happing after the error of Connection refused occurs. I'm guessing this has to do the URI being incorrect. Can you print the URI that is used in:

        uri = 'http://localhost:{}/db/data/'.format(port)
        hetio.neo4j.export_neo4j(graph, uri, 1000, 250)

Then see what that does in your browser. You can comment out finally to keep the server running for debugging (but then you may have to manually kill the neo4j processes in the terminal, e.g. killall neo4j).

veleritas commented 7 years ago

It's running on AWS, so I'll have to try some things to see if I can access the neo4j instance. It seems that the refused connection is occurring even if I comment out the stop command in the finally block.

dhimmel commented 7 years ago

Are you able to get this file from AWS: /home/ubuntu/fold0/integrate/neo4j/neo4j-community-3.1.1_rephetio-v2.0/logs/neo4j.log? That hopefully will have a message for why the server is stopping.

I've simplified the code a little to try and isolate the problem. Right now all it's trying to do is establish a connection to the more default neo4j 3.1.1 (port 7474). Here is the Python traceback I'm getting:

It seems that the problem is that the new binary Bolt interface is the default, and the hetio package is trying to connect to that by default.

dhimmel commented 7 years ago

I think the issue is getting caused by the use of Neo4j 3.x rather than 2.x. Obviously, Neo4j 3.x is better, but it may take some work to upgrade this repo to use 3.x.

The environment.yml specifies py2neo==2.0.8. You could try upgrading to py2neo==3.1.2 (latest):

pip install --upgrade py2neo==3.1.2

That may fix the issue, but I'm worried the py2neo API may have changed in version 3. Worth a try though.

Maybe first check this answer. Could that fix this? (would be odd if that was the issue)

If neither of these fix the issue, we may need to consult the Neo4j slack of slack overflow.

Ah, there may be a way to get bolt to work or to disable it.

veleritas commented 7 years ago

Yes I think I'm going to need to update your hetio package to make it work with Neo4j 3. I'm already on all the latest packages of everything.

dhimmel commented 7 years ago

So do you think the issue is in this line of hetio.neo4j.export_neo4j:

db_graph = py2neo.Graph(uri)
veleritas commented 7 years ago

Yes, in my current testing code I can get the following to work:

def connect(netloc, neo4j_dir):
    neo4j_bin = os.path.join(neo4j_dir, 'bin', 'neo4j')

    subprocess.run([neo4j_bin, 'start'])
    subprocess.run([neo4j_bin, 'status'])

#     temp = Graph("bolt://localhost:7687/db/data")

    temp = Graph(host="localhost", bolt = True)

    temp.delete_all()

    subprocess.run([neo4j_bin, 'status'])

#     graph = hetio.readwrite.read_graph(netloc)
#     uri = 'http://localhost:7474/db/data'
#     hetio.neo4j.export_neo4j(graph, uri, 1000, 250)
    subprocess.run([neo4j_bin, 'stop'])

Connecting to neo4j 3.1.1 directly through py2neo doesn't seem to give me any problems. However I can't specify it to use the new bolt protocol by giving it just a string, as seen in temp = Graph("bolt://localhost:7687/db/data").

There is a setting to turn bolt off in the configuration files, but I'm going to see if I can get things to work with bolt, and resort to the http way if all else fails.

dhimmel commented 7 years ago

Currently, https://neo4j.het.io is running Neo4j 3.1.0 and exposes the following ports: 80, 443, 7687.

py2neo==3.1.2 is struggling, but here is some of my findings:

import py2neo

# Works, but fails without the port (makes sense)
py2neo.Graph('http://neo4j.het.io:80')
# Works, but fails without the port (makes sense)
py2neo.Graph('https://neo4j.het.io:443')

# Fails with and without the port (does not make sense)
py2neo.Graph('bolt://neo4j.het.io:7687')

So I do think py2neo is a bit buggy here as py2neo.Graph('bolt://neo4j.het.io:7687') should work.

@veleritas your issue may be slightly different. The bolt connection cannot use the same port as http(s). The default bolt port is 7687, but it won't work to have multiple neo4j servers open at the same time using that port.

However, it's good that you can get temp = Graph(host="localhost", bolt = True). In the worst case scenario, we could modify hetio so you can pass it a uri or an already opened py2neo.Graph.

veleritas commented 7 years ago

Alright, I think I have figured out what's wrong. It seems like there is nothing wrong with py2neo except that it doesn't play well with neo4j sometimes.

The current situation is that if neo4j is started from the bash terminal by hand using ./neo4j start, and then py2neo tries to establish a connection, then everything works just fine. However, if neo4j is started from Python via a subprocess call, or if the same ./neo4j start command is started from a bash script, then py2neo is no longer able to establish a connection to the database.

I'm not really sure how to solve this though, since manually starting neo4j isn't really the best of options.

veleritas commented 7 years ago

Alright. It turns out that the code needs to wait for 5 seconds (not 4 or less) via a sleep command in order for the connection to work properly. Maddening.

dhimmel commented 7 years ago

Ahh good to know!

I still think there is a py2neo problem as described in https://github.com/technige/py2neo/issues/605. If I'm correct, you'll still have trouble connecting to Neo4j 3.1 using bolt with just at URI.

So it sounds like I don't need to edit hetio, but that a sleep timer should be implemented in neo4j-import.ipynb proceeding:

    neo4j_bin = os.path.join(neo4j_dir, 'bin', 'neo4j')
    subprocess.run([neo4j_bin, 'start'])

However, I would need to update hetio if you want to use bolt and py2neo doesn't address https://github.com/technige/py2neo/issues/605 soon.

I think editing hetio may be inevitable, but I can help you there since I'm already in the process of making edits. Some things in py2neo have changed from version 2 to version 3, so hetio needs to be updated to keep up.

For example, see this issue.

Awesome. If you make a pull request into hetio that's the most helpful. We could then release a v0.3.0. I see you've opened https://github.com/dhimmel/hetio/issues/4, so we can discuss there.

It does seem like the URI interpreter in py2neo has some sort of bug at the moment. Removing the bolt:// from the URI fixes things for me. Strange...
