Kerberos support

Most of Hadoop instances set up with Kerberos support, so some connections require additional setup to work properly.

• HDFS Uses requests-kerberos and GSSApi for authentication. It also uses kinit executable to generate Kerberos ticket.
• Hive and SparkHDFS require Kerberos ticket to exist before creating Spark session.

So you need to install OS packages with:

• krb5 libs
• Headers for krb5
• gcc or other compiler for C sources

The exact installation instruction depends on your OS, here are some examples:

apt install libkrb5-dev krb5-user gcc  # Debian-based
dnf install krb5-devel krb5-libs krb5-workstation gcc  # CentOS, OracleLinux

Also you should pass kerberos to extras to install required Python packages:

pip install "onetl[kerberos]"
