Apache Druid

```The Unable to load native-hadoop library for your platform... using builtin-java classes where applicable warning messages can be safely ignored```
Also, have you followed the configurations:
1. <https://druid.apache.org/docs/latest/tutorials/tutorial-batch-hadoop.html#configure-druid-to-use-hadoop>
2. <https://druid.apache.org/docs/latest/development/extensions-core/hdfs.html>

Thank you very much for your answer. I've been reading this documentation and I'm looking for the reason why the druid won't connect to HDFS, the authentication is done after kerberos.

According to the documentation, I created a keytab file and the logs show that it works.

In the Ranger audit I have no connection to hdfs. When a druid starts, it should connect to HDFS?

I wonder whether this tutorial will be useful for you: <https://druid.apache.org/docs/latest/tutorials/tutorial-kerberos-hadoop.html>
