How to setup a multi user (Active Directory backed) zeppelin integrated with ldap and using Livy Rest server . Pre-requisites: Setup the LDAP/AD integration for ambari using this lab (Enable Active Directory Authentication for Ambari):https://github.com/HortonworksUniversity/Security_Labs#lab-1 If you are using self-signed certificate, Download the SSL certificate to where zeppelin is running <code>mkdir -p /etc/security/certificates store the certificate in this directory Import certificate for zeppelin to work with the self signed certificate. <code>cd /etc/security/certificates keytool -import -alias sampledcfieldcloud -file ad01.your.domain.name.cer -keystore /usr/jdk64/jdk1.8.0_77/jre/lib/security/cacerts keytool -list -v -keystore /usr/jdk64/jdk1.8.0_77/jre/lib/security/cacerts | grep sampledcfieldcloud Create home directory in hdfs for the user that you will login: <code>hdfs dfs -mkdir /user/hadoopadmin hdfs dfs -chown hadoopadmin:hdfs /user/hadoopadmin Enable multi-user zeppelin use ambari -> zeppelin notebook configs expand the Advanced zeppelin-env and look for shiro.ini entry. Below is configuration that works with our sampledcfield Cloud. <code>[users] # List of users with their password allowed to access Zeppelin. # To use a different strategy (LDAP / Database / ...) check the shiro doc at http://shiro.apache.org/configuration.html#Configuration-INISections #admin = password1 #user1 = password2, role1, role2 #user2 = password3, role3 #user3 = password4, role2 # Sample LDAP configuration, for user Authentication, currently tested for single Realm [main] activeDirectoryRealm = org.apache.zeppelin.server.ActiveDirectoryGroupRealm #activeDirectoryRealm.systemUsername = CN=binduser,OU=ServiceUsers,DC=sampledcfield,DC=hortonworks,DC=com activeDirectoryRealm.systemUsername = binduser activeDirectoryRealm.systemPassword = xxxxxx activeDirectoryRealm.principalSuffix = @your.domain.name #activeDirectoryRealm.hadoopSecurityCredentialPath = jceks://user/zeppelin/zeppelin.jceks activeDirectoryRealm.searchBase = DC=sampledcfield,DC=hortonworks,DC=com activeDirectoryRealm.url = ldaps://ad01.your.domain.name:636 activeDirectoryRealm.groupRolesMap = "CN=hadoop-admins,OU=CorpUsers,DC=sampledcfield,DC=hortonworks,DC=com":"admin" activeDirectoryRealm.authorizationCachingEnabled = true sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager cacheManager = org.apache.shiro.cache.MemoryConstrainedCacheManager securityManager.cacheManager = $cacheManager securityManager.sessionManager = $sessionManager securityManager.sessionManager.globalSessionTimeout = 86400000 #ldapRealm = org.apache.shiro.realm.ldap.JndiLdapRealm #ldapRealm.userDnTemplate = uid={0},cn=users,cn=accounts,dc=example,dc=com #ldapRealm.contextFactory.url = ldap://ldaphost:389 #ldapRealm.contextFactory.authenticationMechanism = SIMPLE #sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager #securityManager.sessionManager = $sessionManager # 86,400,000 milliseconds = 24 hour #securityManager.sessionManager.globalSessionTimeout = 86400000 shiro.loginUrl = /api/login [roles] admin = * [urls] # anon means the access is anonymous. # authcBasic means Basic Auth Security # To enfore security, comment the line below and uncomment the next one /api/version = anon /api/interpreter/** = authc, roles[admin] /api/credential/** = authc, roles[admin] /api/configurations/** = authc, roles[admin] #/** = anon /** = authc #/** = authcBasic Grant Livy ability to impersonate Use Ambari to update core-site.xml, restart YARN & HDFS after making this change. <code><property> <name>hadoop.proxyuser.livy.groups</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.livy.hosts</name> <value>*</value> </property> Restart hdfs and yarn after this update. After running the livy notebook make sure the yarn logs show the logged in user as the user that is running, hadoopadmin is the user that is logged in the zeppelin notebook. You should see 2 applications running the livy-session-X and the zeppelin app running in yarn <code>application_1478287338271_0003 hadoopadmin livy-session-0 application_1478287338271_0002 zeppelin Zeppelin Troubleshooting, explore zeppelin and livy log files: <code>tail -f /var/log/zeppelin/zeppelin-zeppelin-az1secure0.log tail -f /var/log/zeppelin/zeppelin-interpreter-livy-zeppelin-az1secure0.log Next Steps: This multi-part article shows how to Secure Spark with Ranger using Zeppelin and Livy for Multi-user access Securing Spark with Ranger using Zeppelin and Livy for Multi-user access - Part 1 References: https://zeppelin.apache.org/docs/0.6.0/interpreter/livy.html#faqhttp://dev.hortonworks.com.s3.amazonaws.com/HDPDocuments/HDP2/HDP-2-trunk/bk_command-line-installation/content/ch21s07s02.html http://dev.hortonworks.com.s3.amazonaws.com/HDPDocuments/HDP2/HDP-2-trunk/bk_command-line-installation/content/configuring_zep.html ...
