Druid Extension not found

I'm trying to load druid-avro-extensions by setting it on druid.extensions.loadList config property, but the broker is not starting beause the extension is not found:

Exception in thread "main" io.druid.java.util.common.ISE: Extension [/usr/hdp/current/druid-broker/extensions/druid-parquet-extensions] specified in "druid.extensions.loadList" didn't exist!?

Edit: the extensions is not located on the spcified directory, but it should be there since it is a core extension. What can I do to fix this issue and why is not the extension there?

What is happening? Thanks.
