who can help me?

surekhasaharan commented 5 years ago

Hey @shaoxinye it seems you might be missing some hadoop jars. What is there in your druid.extensions.loadList ?

liguifa commented 5 years ago

I had the same problem. druid.extensions.loadList=["druid-hdfs-storage", "mysql-metadata-storage", "druid-lookups-cached-global", "druid-kafka-indexing-service", "druid-datasketches", "druid-histogram", "druid-uniq", "materialized-view-maintenance", "materialized-view-selection"]

surekhasaharan commented 5 years ago

do you have "materialized-view-maintenance", "materialized-view-selection" on all the nodes or in common.runtime.properties. This suggests "make sure to only load materialized-view-selection on Broker and load materialized-view-maintenance on Overlord." Also these extensions are not required on router, so you can remove them from your router config.
