JetBrains DataGrip create Impala connection
This is an example of creating a JetBrains DataGrip connection to Impala authenticated by Kerberos on Ubuntu.
We will have to manualy generate a Kerberos ticket before connecting to Impala.
The first thing is to install Kerberos (example provided for Ubuntu). Then get the krb5.conf and the keytab files and then generate the ticket :
sudo apt install krb5-user kinit -V my.user /tmp/my.user.keytab klist
