If you have any problem during the installation of OpenQuake, please check this list before asking on IRC/ML.

java.lang.ExceptionPyRaisable: java.lang.Exception: Class XYZ not found

This is probably due to the OpenQuake jar that is missing. Try to build the jar with:

cd /to/your/openquake/dir/
ant build-openquake-jar

And run the tests suite (or the smoke test) again.

RuntimeError: Unable to start JVM at src/native/common/jp_env.cpp:54

This is probably because the max_mem parameter is set too high in openquake/java.py. Try to decrease it and run the tests suite (or the smoke test) again.

TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘str’

    if os.path.exists(java_home+"/bin/javac") :
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

This is because the JAVA_HOME environment variable is empty. Try to export it again before launching celeryd and rerun the tests suite.

This is because the JAVA_HOME environment variable is set up, but it is pointing to the wrong directory. Try to export it again and rerun the tests suite.

This is because RabbitMQ server is not properly configured. Please look at the Installation page to learn how to properly configure RabbitMQ.

    "Celery needs to be configured to run  celeryd."
celery.exceptions.ImproperlyConfigured: Celery needs to be  configured to run celeryd.

Solution:

Make you are running celeryd from the directory containing celeryconfig.py.

In some cases, the cause of this issue may be an incompatible version of python-gflags. This is indicated by the following error when trying to

import celeryconfig

in a Python console.

~/openquake$ python
Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)
[GCC 4.4.5] on linux2 Type "help", "copyright", "credits" or "license" for more information.
>>> import celeryconfig

Traceback (most recent call last):

File "", line 1, in
File "celeryconfig.py", line 11, in  from openquake import flags
File "openquake/flags.py", line 9, in  from gflags import *
File "/usr/local/lib/python2.6/dist-packages/gflags.py", line 396, in

Make sure you have the proper version of python-gflags installed. Check out the Installation page for more information.

Exception on [GET] => ERR unknown command ‘some value’ (error with JRedis)

A Java error like this might appear in response to a Redis ‘get’ command. You can use the following test code to confirm the error:

import java.net.InetSocketAddress;

import org.jredis.RedisException;
import org.jredis.connector.ConnectionSpec;
import org.jredis.ri.alphazero.JRedisClient;
import org.jredis.ri.alphazero.connection.DefaultConnectionSpec;

/**
 * Note: You may need to adjust to connection spec, host, and port
 * parameters to suit your environment.
 */
public class RedisTest {
    
    public static void main (String [] args) {
        InetSocketAddress addr = new InetSocketAddress("localhost", 6379);
        ConnectionSpec cs = DefaultConnectionSpec.newSpec();
        cs.setAddress(addr.getAddress())
            .setPort(addr.getPort())
            .setReconnectCnt(2)
            .setDatabase(0);
        JRedisClient client = new JRedisClient(cs);
        
        try {
            client.set("test_key", "test_value");
            String value = new String(client.get("test_key"));
            System.out.println(value);
        } catch (RedisException e) {
            e.printStackTrace();
        }
    }
}

The full error should look something like this:

Exception on [GET] => ERR unknown command ‘test_value’

	at org.jredis.ri.alphazero.connection.SynchConnection.serviceRequest(SynchConnection.java:170)

	at org.jredis.ri.alphazero.JRedisClient.serviceRequest(JRedisClient.java:151)

	at org.jredis.ri.alphazero.JRedisSupport.get(JRedisSupport.java:950)

	at RedisTest.main(RedisTest.java:25)

Cause:

This error appears to be caused by an incompatibility between the JRedis library used for OpenQuake and the installed version of the Redis server. In our tests, this error appeared with redis-server version 2.2.2.

Solution:

Try uninstalling redis-server and reinstall a known-working version, such as 2.0.4.
