DB Visualizer is a popular free tool that allows developers to organize development tools for RDBMS development. With Apache Phoenix, that allows SQL like capability for Hbase, we can use DBVisualizer to connect to Apache Phoenix layer for HBase. Verified with following versions. DBVisualizer version 9.2.12 hbase-client-1.1.2.2.3.2.0-2950.jar phoenix-4.4.0.2.3.2.0-2950-client.jar First Add Phoenix driver to DBVisualizer. In DBVisualizer, go to Tools->Driver Manager and add a new driver. Add both hbase-client and phoenix-client jar. This will add a new Phoenix driver. 1. Connecting to Non-Kerberos cluster To connect to a Non-Kerberos cluster, use jdbc:phoenix:<zookeeper host>:<zookeeper port>:<hbase_z_node> as connection string where hbase_z_node is :/hbase by default. 2. Connecting to Kerberos cluster using cached ticket To connect to a Kerberos cluster, a. add following files to DBVisualizer resources directory. hdfs-site.xml hbase-site.xml core-site.xml b. Copy krb5.conf file to local workstation. c. Create a jaas file with following entry. Client {
com.sun.security.auth.module.Krb5LoginModule required useTicketCache=true renewTicket=true
serviceName="zookeeper";}; Modify dbvisgui.bat file to add following parameters for launching DBVisualizer -Djava.security.auth.login.config="<path-to-jaas-file>" -Djava.security.krb5.conf="<path-to-krb5-file>" d. Connection string for cached keytab will be jdbc:phoenix:<zookeeper host>:<zookeeper port>:/hbase-secure:<path-to-jaas file> 3. Connecting to Kerberos cluster using keytab a. add following files to DBVisualizer resources directory.
hdfs-site.xml
hbase-site.xml
core-site.xml b. Copy krb5.conf file to local workstation. c. copy keytab file use for connecting to Hbase. d. Create a jaas file with following entry. Client {
com.sun.security.auth.module.Krb5LoginModule
requireduseTicketCache=false
useKeytab=true
serviceName="zookeeper";}; Connection string for this case will be jdbc:phoenix:<zookeeper host>:<zookeeper port>:/hbase-secure:<Principal>:<path-to-keytab> Sample connection string jdbc:phoenix:host0001:2181:/hbase-secure:<principal>:\users\z_hadoop_test.keytab Test your connection !
