Julien,
I have an empty drill-module.conf file in the udf jar file. Below are the
contents of my global drill-override.conf file
drill.classpath.scanning.packages : ${?drill.classpath.scanning.packages} [
org.apache.drill.udfs ]
drill.exec: {
cluster-id: "rahul_cluster_com-drillbits",
zk.connect: "localhost:5181"
}
With this, the drillbit fails to start with the error I posted in the first
email. May be I am getting the syntax wrong?
The reason I am insisting an empty drill-module.conf file is because, udf's
developed prior to the "classpath scanning change" had an empty
drill-module.conf file and we used to override the udf package name in the
global conf file.
