Any debugging

I don't know if this is correct, but i searched the source code here which using module org.apache.hadoop.fs.FileSystem, which i found later in the pom.xml only include hadoop-common as dependency (according to this SO thread you must use hadoop-hdfs instead)

11noskcire commented 3 years ago

for now i solved it with manually copying the hadoop-hdfs-client.jar to druid-ranger-security extension folder

cp druid/extensions/druid-hdfs-storage/hadoop-hdfs-client-2.8.5.jar druid/extensions/druid-ranger-security/
