Hi, There are many etl tools in market. I did some research on Pentaho Data Integraion Tool. In which kettle is for ETL. How can we compare kettle with hadoop ? Does kettle(any ETL tool) replaces hadoop ? When do we need ETL tool on the top of hadoop ? Please someone help me to clear my doubts. Thanks, Heta

Hi, In LDAP we create users and sync them with cluster, Ambari and Ranger, so same user can be used everywhere. I have configured my cluster for kerberos. How can i achieve centralized user authentication in kerberos enabled cluster as i mentioned above we can do in LDAP ? I do not have LDAP server. I want to do Authentication and Authorization both using Kerberos only. Thanks, Heta

@Jonathan Sneep After downloading jce8 i am not able to unzip it. It shows below error: Archive: jce_policy-8.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of jce_policy-8.zip or jce_policy-8.zip.zip, and cannot find jce_policy-8.zip.ZIP, period. I am using this doc.

Hi, I want to provide user authentication and resource/service authority to my cluster. I do not have LDAP server. I want to use Kerberos for my cluster security. How can I configure and start using kerberos without LDAP ? I have followed this link but i don't what is next step ? How can i integrate kerberos with Ambari ? For now i am trying on sandbox HDP 2.6.5. Thanks, Heta

Hi, I am using cloudbreak data platform on azure. My company has own authorization tool for user authorization. Is it possible to use this tool with cluster created on cloudbreak for user security management ? Same concern with HDinsight on Azure ? Thanks, Heta

Hi, I am using sandbox HDP 2.6.5 in virtualbox. I have configured Kylin 2.6.0. Kylin started successfully but i am not able to open Kylin Web UI. So i need to add Port 7070 to sandbox and for that i am following this article which is for HDP 2.5. As defined in the article to add port i have to edit start_sandbox.sh file under /root/start_scripts directory. But there is no directory named start_scripts under /root. I am facing same issue for HDP 3.0. So, how can i add new port in HDP 2.6.5/3.0 ? Thanks, Heta

heta_desai · ‎03-14-2019

@Jay Kumar SenSharma I can successfully login to Amabri in Incognito Mode in Gogle Chrome. I am running one HDP sandbox instance at a time, but i am using different versions so i think the issue i was facing is due to caching. Thank you so much.

heta_desai · ‎03-14-2019

@Jay Kumar SenSharma In browser when i try to login to Ambari using login credentials it shows "server error".

Hi, I have 3 versions of HDP in oracle virtual box. The versions are 2.5, 2.6.5 and 3.0. When i start VM for HDP 3.0 the Ambari UI works fine. But after that if i start VM for HDP lower versions 2.5 or 2.6.5 i can not open Ambari UI. It shows Server error. Based on the requirement i need to use different versions of HDP. How can i resolve this issue ? Thanks, Heta

#TO CHANGE KYLIN UI PORT 1. cd /usr/local/apache-kylin-2.6.0-bin/tomcat/conf 2. Open server.xml Change port in Connector Port argument: As shown below Connector Port 7070 is assigned.

When i use WASB as storage, while creating cluster i need to have Master node and compute nodes only right ? No need to have worker node as i am using WASB not HDFS ?

heta_desai · ‎02-12-2019

@lnardai It worked for me. What does it mean "wrap it as a service" ?

heta_desai · ‎02-12-2019

Hi, I have launched cloudbreak hortonworks data platform on Azure. The url was working properly before VM restarted. When I restart the vm the url is not working. Is there any other way to open cloudbreak UI ? Thank you

heta_desai · ‎02-11-2019

so there is no replication mechanism if i use WASB as default storage ?

heta_desai · ‎02-11-2019

@Dominika Bialek So i can use WASB as a default storage right ? and compute node can read data from WASB for processing ?
