Hive instances

Here you may find dockerized hive configurations.

Prerequisites

You should use a *nix system with pre-installed:

  • docker

  • docker-compose

  • krb5-user (for Debian) # in case you want use kerberized Hive

  • Open JDK

Pre-install

Firstly, you should build images and configure certs:

make build VERSION=2.3.6

make generate_ssl

Usage

To use Hive instance you should run:

make up TYPE=<type> # run

make down # stop

make log # watch hive-server logs

where <type> is the suffix of hive-site.xml configs in the folder confs/.

Example:

make up TYPE=tcp.nosasl

To run kerberized Hive instance run:

make up-krb TYPE=tcp.kerberos

kinit hive@KERBEROS.SERVER

password: hive

To stop instance:

Set up kerberos client

To use kerberized Hive you should install and set up krb5 client.

For Ubuntu you should install krb5-user:

sudo apt install krb5-user

Then add to /etc/hosts

127.0.0.1 KERBEROS.SERVER
127.0.0.1 kerberos.server

And add to /etc/krb5.conf next configuration:

[libdefaults]
    default_realm = KERBEROS.SERVER
[realms]
    KERBEROS.SERVER = {
        kdc = kerberos.server
        admin_server = kerberos.server
    }
[domain_realm]
    .kerberos.server = KERBEROS.SERVER
    kerberos.server = KERBEROS.SERVER

Afteward you may obtain a ticket from dockerized Kerberos server:

make kinit
