Introducing Hortonworks Data Cloud
 Focuses on business agility, rather than
infinite configurability and cluster
management
 Addresses prescriptive, ephemeral use
cases around Apache Spark + Apache Hive
 Pre-tuned and configured for use with

Apache Knox Proxying Services
★ Provide access to Hadoop via proxying of
HTTP resources
★ Ecosystem APIs and UIs + Hadoop oriented
dispatching for Kerberos + doAs
(impersonation) etc.
Authentication Services
★ REST API access, WebSSO flow for UIs
★ LDAP/AD, Header based PreAuth
★ Kerberos, SAML, OAuth
Client DSL/SDK Services
★ Scripting through DSL
★ Using Knox Shell classes directly as SDK

Apache Ranger
Comprehensive and Extensible Security Model
– Centralized platform to define, administer and manage
security policies across Hadoop components (HDFS, Hive,
HBase, YARN, Kafka, Solr, Storm, Knox, NiFi, Atlas)
– Extensible Architecture with ability to add custom policy
conditions, user context enrichers
Centralized Auditing
– Central audit location for all access requests
– Support multiple destination sources (HDFS, Solr, etc.)
– Real-time visual query interface
Fine-Grained Authorization
for data access control for Database, Table, Column, LDAP
Groups & Specific Users
Advanced Security
• Dynamic Security Policies: Tag (Atlas), Prohibition, Time, and
Location
• Dynamic Column Masking & Row Filtering

Metadata-driven governance services for Hadoop and
enterprise big data ecosystems
Data Lineage/Provenance
 Along the entire data lifecycle with integrated Cross
component lineage
Data Classification
 Supports classification of data assets using tags (e.g. PII,
PHI, PCI etc.) and attributes
Metadata Catalog Search
 Free text search on metadata
 Advanced search using DSL
Integrations
across the Hadoop ecosystem, through a common metadata
store
 Free text search on metadata
 OOtB real-time metadata and lineage ingestion with Hive,
Sqoop, Storm/Kafka
 APIs for custom metadata ingestion
 Apache Ranger integration for classification based security
Key Benefits:
Modern Data Lakes need new ways to
govern because:
• Cost – Traditional staff ratio to data size not possible
• Diversity – Only way to manage velocity of new datasets
• Agility – Quick change based on tags / taxonomy

SHARED DATA LAKE SERVICES

Key Components for an Enterprise Ephemeral Deployment
SCHEMA POLICY AUDIT DIRECTORY
WHAT
Provides Hive schema (tables,
views, etc).
WHY
If you have 2+ workloads
accessing the same data, need
to share schema across those
workloads.
HOW
Externalize Hive Metastore
into for schema definition.
WHAT
Defines security policies
around Hive schema.
WHY
If you have 2+ users accessing
the same data, need policies
to be consistently available
and enforced.
HOW
Externalize and share Ranger
across workloads and store
policies external.
WHAT
Audit user access.
WHY
Capture data access activity.
HOW
Externalize and share Ranger
across workloads, leverage
cloud storage for audit data.
GATEWAY
WHAT
Provide single endpoint that
can be protected with SSL and
enabled for authentication to
access to cluster resources.
WHY
Avoid opening many ports,
some potentially w/o
authentication or SSL
protection.
HOW
Deploy a centralized protected
gateway automatically.
WHAT
Users and groups.
WHY
Provide authentication source
for users and authorization
source for groups.
HOW
Leverage external LDAP or
Active Directory.

Architecture of an Enterprise Ephemeral Deployment
Access your cluster
components through the
protected gateway via SSL
on port 443 open on the
controller security group.

Register an Authentication Source (i.e. LDAP/AD).
Create a “Shared Data Lake”, specify S3 Bucket & RDS.
When you create a cluster, ”attach” to the Shared Data Lake Services:
• for Multi-User AuthN (LDAP/AD)
• for AuthZ + Audit (Ranger)
• for Schema (Hive Metastore)
PREREQUISITES
• LDAP/AD
• S3 Bucket
• Amazon RDS Instance

Longer demo…

Guidelines for Shared Data Lake Services
 Stay Ephemeral. All of your data and metadata in S3 and RDS respectively, do not create
tables or files in the local HDFS.
 The Hive warehouse is setup to be on S3 for data lakes, create tables in this location
instead of individual S3 buckets, it will make them easier to manage.
 Use Hive “external tables” for tables that are outside this warehouse, typically if the
data is being ingested through some path outside of Hadoop
 Create S3 bucket policies that exactly match usage so that you can spin up clusters with
the least privilege.

Wrap Up

Bringing Big Data + Cloud + Security Together: The Takeaways
 Cloud driving more ephemeral data processing use cases
 Ephemeral workloads leverage cloud storage
 This pattern is driving an architectural approach for “shared data lake services”
 To provide shared security services for Authentication, Authorization and Audit
** Building blocks are Apache Ranger, Apache Atlas and Apache Knox
THINK
WORKLOADS
Deploy “what you need”…
Right tool, right job!
THINK
SHARED
Shared “security policies”…
End-to-end security for workloads!**
THINK
EPHEMERAL
Run “when you need”…
Workloads will come and go!
