Pirates Hive Security Quest

Introduction

The Black Pearl, a notorious pirate ship, has just docked at the shores of a mysterious island rumored to be the resting place of an ancient treasure. Captain Jack Sparrow, the cunning and charismatic pirate leader, has enlisted the help of Tia Dalma, a powerful voodoo mystic, to guide them through the island's treacherous jungles and unlock the secrets of the treasure's location. However, the journey will not be easy, as they must navigate through a series of challenges that test their knowledge and skills in securing Hadoop Hive, a crucial component of the island's mystical defenses.

The objective is to overcome these challenges and secure access to the treasure, proving their mastery over Hadoop Hive's security measures. Only by unraveling the island's mysteries and demonstrating their prowess in securing Hive will they be able to claim the legendary riches that await them.

Establishing a Secure Hive Metastore

In this step, you will learn how to configure a secure Hive Metastore, a crucial component that stores the metadata for Hive databases, tables, and partitions. By securing the Metastore, you will ensure that sensitive information is protected from unauthorized access.

1. First, ensure you are logged in as the hadoop user by running the following command in the terminal:

su - hadoop

2. Create a new directory called hive-secure in your home directory:

mkdir ~/hive-secure

3. Navigate to the hive-secure directory:

cd ~/hive-secure

4. Create a new file called hive-site.xml and add the following configuration:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>hive.metastore.uris</name>
    <value>thrift://localhost:9083</value>
    <description>Metastore URI to connect to</description>
  </property>
  <property>
    <name>hive.metastore.sasl.enabled</name>
    <value>true</value>
    <description>Enable SASL for Metastore</description>
  </property>
  <property>
    <name>hive.metastore.kerberos.principal</name>
    <value>hive/_HOST@EXAMPLE.COM</value>
    <description>Kerberos principal for Metastore</description>
  </property>
</configuration>

This configuration sets up a secure Metastore using Kerberos authentication. The hive.metastore.sasl.enabled property enables SASL (Simple Authentication and Security Layer) for the Metastore, while the hive.metastore.kerberos.principal property specifies the Kerberos principal for the Metastore service.

5. Copy the hive-site.xml file to the Hive configuration directory:

cp hive-site.xml /usr/local/hive/conf/

After completing these steps, you will have successfully configured a secure Hive Metastore using Kerberos authentication.

Enabling Hive Authorization With Apache Ranger

In this step, you will learn how to secure Hive by enabling authorization using Apache Ranger, a comprehensive security solution for Hadoop clusters.

1. Create a new directory called ranger-hive in your home directory:

mkdir ~/ranger-hive

2. Navigate to the ranger-hive directory:

cd ~/ranger-hive

3. Create a new file called ranger-hive-security.xml and add the following configuration:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>hive.security.authorization.manager</name>
    <value>org.apache.ranger.authorization.hive.authorizer.RangerHiveAuthorizerFactory</value>
    <description>Hive authorization manager</description>
  </property>
  <property>
    <name>hive.security.authorization.enabled</name>
    <value>true</value>
    <description>Enable Hive authorization</description>
  </property>
  <property>
    <name>hive.security.authenticator.manager</name>
    <value>org.apache.hadoop.hive.ql.security.SessionStateUserAuthenticator</value>
    <description>Hive authenticator manager</description>
  </property>
</configuration>

This configuration enables Hive authorization using Apache Ranger. The hive.security.authorization.manager property specifies the Ranger Hive authorizer factory, while the hive.security.authorization.enabled property enables Hive authorization. The hive.security.authenticator.manager property sets the authentication manager for Hive sessions.

4. Copy the ranger-hive-security.xml file to the Hive configuration directory:

cp ranger-hive-security.xml /usr/local/hive/conf/

After completing these steps, you will have successfully enabled Hive authorization using Apache Ranger.

Configuring Hive Encryption

In this step, you will learn how to configure Hive encryption to protect sensitive data stored in Hive tables and partitions.

1. Create a new directory called hive-encryption in your home directory:

mkdir ~/hive-encryption

2. Navigate to the hive-encryption directory:

cd ~/hive-encryption

3. Create a new file called hive-encryption.xml and add the following configuration:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>hive.server2.enable.doAs</name>
    <value>false</value>
    <description>Enable impersonation for HiveServer2</description>
  </property>
  <property>
    <name>hive.exec.dynamic.partition.mode</name>
    <value>nonstrict</value>
    <description>Hive dynamic partition mode</description>
  </property>
  <property>
    <name>hive.crypto.codec</name>
    <value>com.my.codec.AesCodec</value>
    <description>Codec for Hive encryption</description>
  </property>
  <property>
    <name>hive.crypto.codec.implementation</name>
    <value>com.my.codec.AesCodecImplementation</value>
    <description>Implementation for Hive encryption codec</description>
  </property>
</configuration>

This configuration enables Hive encryption using a custom codec implementation. The hive.crypto.codec property specifies the codec class for encryption, while the hive.crypto.codec.implementation property specifies the implementation class for the encryption codec.

The hive.server2.enable.doAs property disables impersonation for HiveServer2, and the hive.exec.dynamic.partition.mode property sets the dynamic partition mode to non-strict for compatibility with encryption.

4. Copy the hive-encryption.xml file to the Hive configuration directory:

cp hive-encryption.xml /usr/local/hive/conf/

After completing these steps, you will have successfully configured Hive encryption using a custom codec implementation.
