Kerberos Authentication for HDFS

Kerberos Authenticaiton for HDFS. #16621 (Ilya Golshtein).
Kerberos Authentication Support for HDFS in ClickHouse.

Why it matters

This feature enables secure and authenticated access to HDFS clusters using Kerberos authentication. It solves the problem of integrating ClickHouse with Kerberos-secured Hadoop environments, thereby enhancing security and compliance when accessing data stored in HDFS.

How to use it

To use Kerberos authentication with HDFS in ClickHouse, ensure your HDFS cluster is configured for Kerberos. Then configure ClickHouse's HDFS settings to use the appropriate Kerberos keytab and principal. Typically, this involves setting the relevant parameters in the ClickHouse configuration files related to HDFS connectivity and authentication.
