Bad artifact coordinates raised when start coordinator in 0.8.3


I’m trying to setup a new druid cluster 0.8.3, because caravel didn’t support druid 0.9

when I start coordinator node, it says

Exception in thread “main” java.lang.IllegalArgumentException: Bad artifact coordinates postgresql-metadata-storage:0.8.3, expected format is :[:[:]]:

at org.eclipse.aether.artifact.DefaultArtifact.(

at org.eclipse.aether.artifact.DefaultArtifact.(

at io.druid.initialization.Initialization.getClassLoaderForCoordinates(

at io.druid.initialization.Initialization.getFromExtensions(

at io.druid.cli.Main.main(

this is how I setup druid server, I google but didn’t found anything helpful

any hint helps, thanks


tar -xf druid-0.8.3-bin.tar.gz

rm -f druid-0.8.3-bin.tar.gz

mv druid-0.8.3 druid

cd drui/

editing config/_common/ here

java -Xmx512m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath “config/_common:config/coordinator:lib/*” io.druid.cli.Main server coordinator

Try druid.extensions.coordinates=[“io.druid.extensions:postgresql-metadata-storage:0.8.3”]

thanks and I’ll try again later

I switch to druid 0.9 yesterday

Even better :wink:
