Docker file for Hive Metastore 3 standalone

About

Example of running standalone Hive Metastore. Minio is used as S3 storage for external tables.

It contains following containers:

  • mariadb as dependency
  • minio to test S3 access (make sure that you specify correct volume to be mounted)
  • hive metastore 3.x
  • Pyspark 3.3.x and Pandas

How to run

use docker compose to build && start hive

$ docker-compose build
$ docker-compose up -d

You can now connect to it using hive or spark application.

Hive

Download and untar hive first.
Then copy conf/metastore-site.xml to hive $HIVE_HOME/conf/hive-site.xml

Before running hive make sure you export:

export JAVA_HOME=/java/home
export HADOOP_HOME=/your/local/hadoop/path
export HADOOP_CLASSPATH=${HADOOP_HOME}/share/hadoop/tools/lib/aws-java-sdk-bundle-1.11.375.jar:${HADOOP_HOME}/share/hadoop/tools/lib/hadoop-aws-3.2.0.jar

HADOOP_CLASSPATH is not mandatory if you do not want to use S3

then run:

$ $HIVE_HOME/bin/hive

you shuld see some hive objects if connection works correctly

hive> show tables;
OK
