Hi @Bender    I still not convinced. If that is the case then why binaries of HDF 3.3.0 of SLES SP1 is still available for public  but not moved to paywall? In the Release notes of HDF 3.3.0 why SLES SP3 link is not provided for public ?  Considering same version of HDF but only differences here is OS version    Refer here: https://docs.cloudera.com/HDPDocuments/HDF3/HDF-3.3.0/release-notes/content/hdf_repository_locations.html Table 3. SLES 12 HDF repository & additional download locations I can only see binaries for SUSE Linux Enterprise Server (SLES) v12 SP1 but not SLES V12 SP3 why ?     ... View more

Hello @Bender    I will not agree to your solution.  The reason is,  As per cloudera documentation it says - "Starting with the Ambari 2.7.5 release, access to Ambari repositories requires authentication. To access the binaries, you must first have the required authentication credentials (username and password)." https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/access_ambari_paywall.html So, its very clear that cost to pay for binaries are from Ambari 2.7.5 and later release only.  What i'm asking in this post is, the link to download the "HDF 3.3.0 binaries for SLES 12 SP3"  Note: Support matrix always says SLES 12 SP3 is supported with HDF 3.3.0. But if you open release notes of HDF 3.3.0, i dont see any option to download the HDF and HDF management pack for SLES 12 SP3.  Release Notes contains link to download for SLES 12 SP1 only.   If you go through the support matrix, it says "AMBARI 2.7.3 is the last version that is supported/compatible with HDF 3.3.0" which means there is no need to pay for downloading binaries for HDF 3.3.0 and as well as binaries for AMBARI 2.7.3. Hope my understanding is clear !!     Thanks       ... View more

Thanks for your reply To arrive HDF 3.4.0, we also have to upgrade our Ambari as well. Basically we have two separate HDF and HDP clusters. Currently we are planning to upgrade only HDF cluster. We will not touch HDP cluster Current HDF version = 3.0.2 Current Ambari version = 2.6.1 So, my question is, what should be my upgrade sequence since I need to upgrade Ambari as well along with HDF ? Note, HDF version 3.1.0 is NOT compatible with Ambari version 2.7.3. Can you recommend which of the below sequence will be good to follow ? Sequence#1: Step 1) Upgrade first HDF to 3.1.0 from 3.0.2 This is because HDF 3.1.0 is compatible with Ambari 2.6.1 At the end of this upgrade you will have HDF version 3.1.0 and Ambari version 2.6.1 The first step in upgrading the HDF 3.1 is to upgrade to Ambari 2.6.1. Step 2) Upgrade Ambari alone to 2.7.3 from 2.6.1 At the end of this upgrade you will have HDF version 3.1.0 and Ambari version 2.7.3 Ref - https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.3.0/ambari-managed-hdf-upgrade/content/hdf-upgrade-paths.html Note: HDF version 3.1.0 is NOT compatible with Ambari version 2.7.3 Step 3) Upgrade “HDF” component to 3.3.0 from 3.1.0 At the end of this upgrade you will have HDF version 3.3.0 and Ambari version 2.7.3 HDF version 3.3.0 is compatible with Ambari version 2.7.3 Step 4) Upgrade “HDF” component to 3.4.0 from 3.3.0 At the end of this upgrade you will have HDF version 3.4.0 and Ambari version 2.7.3 HDF version 3.4.0 is compatible with Ambari version 2.7.3 OR Sequence#2: Step 1) Upgrade Ambari alone to 2.7.3 from 2.6.1 At the end of this upgrade you will have HDF version 3.0.2 and Ambari version 2.7.3 Note: HDF version 3.0.2 is NOT compatible with Ambari version 2.7.3 Step 2) Upgrade HDF to 3.1.0 from 3.0.2 At the end of this upgrade you will have HDF version 3.1.0 and Ambari version 2.7.3 Note: HDF version 3.1.0 is NOT compatible with Ambari version 2.7.3 Step 3) Upgrade “HDF” component to 3.3.0 from 3.1.0 At the end of this upgrade you will have HDF version 3.3.0 and Ambari version 2.7.3 HDF version 3.3.0 is compatible with Ambari version 2.7.3 Step 4) Upgrade “HDF” component to 3.4.0 from 3.3.0 At the end of this upgrade you will have HDF version 3.4.0 and Ambari version 2.7.3 HDF version 3.4.0 is compatible with Ambari version 2.7.3 Thanks Chethan ...
