Configuration Storage for Apache Zeppelin

Overview

Zeppelin has lots of configuration which is stored in files:

• interpreter.json (This file contains all the interpreter setting info)
• notebook-authorization.json (This file contains all the note authorization info)
• credential.json (This file contains the credential info)

Configuration Storage in hadoop compatible file system

Set following properties in zeppelin-site.xml:

<property>
    <name>zeppelin.config.storage.class</name>
    <value>org.apache.zeppelin.storage.FileSystemConfigStorage</value>
    <description>configuration persistence layer implementation</description>
</property>
<property>
    <name>zeppelin.config.fs.dir</name>
    <value></value>
    <description>path on the hadoop compatible file system</description>
</property>

Also specify HADOOP_CONF_DIR in zeppelin-env.sh so that Zeppelin can find the right hadoop configuration files.

If your hadoop cluster is kerberized, then you need to specify zeppelin.server.kerberos.keytab and zeppelin.server.kerberos.principal

Configuration Storage in local file system

By default, zeppelin store configuration on local file system.

<property>
    <name>zeppelin.config.storage.class</name>
    <value>org.apache.zeppelin.storage.LocalConfigStorage</value>
    <description>configuration persistence layer implementation</description>
</property>
<property>
    <name>zeppelin.config.fs.dir</name>
    <value></value>
    <description>path on local file system</description>
</property>
