Intro

Concept

Flow Summary

• The java class is configured to

• have the hbase-site.xml, core-site.xml & hdfs-site.xml in classpath
• read a property file for jdbc url, query and name of the column to read

• hbase-site.xml, core-site.xml & hdfs-site.xml tell the program to use KERBEROS auth instead of SIMPLE

• JDBC url tells program the keytab and principal to use for KERBEROS auth

• JVM argument tell the location of KDC via krb5.conf file and tell program on how to authenticate the user

Things to know

• JDBC URL Format - TBD

• Windows Client vs Mac Client - TBD

Note

Setup tested on HDP2.5.3

Usage

Setup

. Add following files from your environment 
	- auth/krb5.conf 
	- auth/smokeuser.headless.keytab  (Keytab for the actual end user - name whatever you want)

	- conf/core-site.xml
	- conf/hdfs-site.xml
	- get phoenix client jar - phoenix-4.7.0.2.6.0.0-597-client.jar - and add it to ./lib/
	
. Update the configuration file 
	- Update ./conf/app.conf and update the JDBC Url, Query and Column to read
