This guide was generated in Jan-Feb'2014 timeframe. Using the feature of SAP HANA Smart Data Access(SDA), it is possible to access remote data, without having to replicate the data to the SAP HANA database beforehand. The following are supported as sources(till 2013): - Teradata database, - SAP Sybase ASE, - SAP Sybase IQ, - Intel Distribution for Apache Hadoop, - SAP HANA. SAP HANA handles the data like local tables on the database. Automatic data type conversion makes it possible to map data types from databases connected via SAP HANA Smart Data Access to SAP HANA data types. This guide will explain the step-by-step approach SAP HANA SDA for Hadoop data - which also include the following : - Hadoop Installation - Data Load in Hadoop system - Activities on Unstructured Data in Hadoop system - ODBC Driver installation & configuration on HANA Server for Hadoop system data access - Smart Data Access in SAP HANA (through SAP HANA Studio), using HADOOP as a remote data source Setup used for this guide : 1) Hadoop : HDP 1.3 for Windows(Hortonworks Data Platform) - Standalone - on Dell Laptop, OS Win7 64bit with 8GB RAM 2) SAP HANA Sever : running on VM – 24GB Standalone HANA 1.0 SPS 7 – SLES 11 SP1

SAP HANA Smart Data Access
Using the feature of SAP HANA Smart Data Access, it is possible to access remote data, without having to replicate the
data to the SAP HANA database beforehand. The following are supported as sources(till 2013):
 Teradata database,
 SAP Sybase ASE,
 SAP Sybase IQ,
 Intel Distribution for Apache Hadoop,
 SAP HANA.
SAP HANA handles the data like local tables on the database. Automatic data type conversion makes it possible to map
data types from databases connected via SAP HANA Smart Data Access to SAP HANA data types.
Steps/Procedure :
 Hadoop Installation
 Data Load in Hadoop system
 Activities on Unstructured Data in Hadoop system
 ODBC Driver installation & configuration on HANA Server for Hadoop system data access
 Smart Data Access in SAP HANA (through SAP HANA Studio), using HADOOP as a remote data source
Assumption – SAP HANA System is already up & running.
Scenario / Lab Setup Details :
1) Hadoop Installation Pre-requisite : HDP 1.3 for Windows(Hortonworks Data Platform) - Standalone
2) Hadoop Installation : HDP 1.3 for Windows(Hortonworks Data Platform) - Standalone – on Dell Laptop, OS Win7
64bit – 8GB)
3) SAP HANA Sever Installation(Lab Server running on VM – 24GB Standalone HANA 1.0 SPS 70) – SLES 11 SP1
4) Validation of Hadoop Installation
5) Data Load in Hadoop system : eBook Upload
6) Unstructured Data transformation into table/views, so that HANA Server can understand Hadoop data.
7) ODBC Driver installation & configuration on HANA Server
8) Smart Data Access in SAP HANA (through SAP HANA Studio), using Hadoop as a remote data source

Services were not started due to 0 bytes in .xml files(master & regionserver)
Also rest/thrift/thrift2.xml are also of zero bytes.
Prepared by Debajit Banerjee Page 17

18. SAP HANA Smart Data Access using Hadoop/Hive
1) Navigate to the hbase install directory: C:hdphadoophbase-0.94.6.1.3.0.0-0380bin
2) Open the hbase.cmd in a text editor
3) Look for the line that says:
set PATH=%PATH%;%HADOOP_HOME%bin
4) Delete it or comment it out with a @rem
Now Open a command prompt and navigate to hbase install: C:hdphadoophbase-0.94.6.1.3.0.0-0380bin
Rebuild the .xml files:
hbase.cmd --service master start > master.xml
hbase.cmd --service regionserver start > regionserver.xml
hbase.cmd --service rest > rest.xml
hbase.cmd --service thrift > thrift.xml
hbase.cmd --service thrift2 > thrift2.xml
