I'm trying to start Graphhopper in hybrid mode using the latest code from its git repo.
The config file, per its comments and documentation (and this answer) has:
prepare.ch.weightings: no
prepare.lm.weightings: fastest
I build it with docker build -t tgraphhopper:lastest . and then I start one container with docker run --name tgraphhopper -v ./data:/data -p 8989:8989 tgraphhopper:latest
The error which appear in logs is:
java.lang.IllegalStateException: Configured graph.ch.weightings: [] is not equal to loaded [fastest|car] at com.graphhopper.storage.GraphHopperStorage.loadExisting(GraphHopperStorage.java:254) at com.graphhopper.GraphHopper.load(GraphHopper.java:781) at com.graphhopper.GraphHopper.importOrLoad(GraphHopper.java:637) at com.graphhopper.http.GraphHopperManaged.start(GraphHopperManaged.java:71) at io.dropwizard.lifecycle.JettyManaged.doStart(JettyManaged.java:27) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:68) at org.eclipse.jetty.util.component.ContainerLifeCycle.start(ContainerLifeCycle.java:138) at org.eclipse.jetty.server.Server.start(Server.java:419) at org.eclipse.jetty.util.component.ContainerLifeCycle.doStart(ContainerLifeCycle.java:117) at org.eclipse.jetty.server.handler.AbstractHandler.doStart(AbstractHandler.java:113) at org.eclipse.jetty.server.Server.doStart(Server.java:386) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:68) at io.dropwizard.cli.ServerCommand.run(ServerCommand.java:53) at io.dropwizard.cli.EnvironmentCommand.run(EnvironmentCommand.java:44) at io.dropwizard.cli.ConfiguredCommand.run(ConfiguredCommand.java:87) at io.dropwizard.cli.Cli.run(Cli.java:78) at io.dropwizard.Application.run(Application.java:93) at com.graphhopper.http.GraphHopperApplication.main(GraphHopperApplication.java:33)
What am I missing in tyring to start the Graphhopper in hybrid mode?
You need to remove the (potentially) created cache folder for the graph in /data
(So, if you have area-latest.osm.pbf the folder is named area-latest.osm-gh)
