Have you set JAVA_HOME correctly? Ambari by default install java at /usr/jdk64 Yes, the jdk 1.8 exists at /usr/jdk64 but I assumed that Ambari sets the JAVA_HOME because if one selects the 'Custom JDK' option during ambari server set-up, it prompts for providing the JAVA_HOME. I am just wondering how Ambari accesses Java
However not sure of you have other dependencies on internet. If the repositories and JDK is now available locally, will Ambari still try to access the Internet? Can you elaborate on the other dependencies ?

Machines : (4 datanodes + 2 master(HA) + 1 management = 7 machines) . Target : Install Ambari 2.2 and using it, install HDP 2.4(the auto. install way). The Ambari and HDP repositories are available locally(on the management node, tarballs were extracted) via http. Ambari server is already running on the management machine and now the HDP 2.4 has to be installed. Questions : To avoid installing JDK on the management(and others, too) machine, the Internet access to http://public-repo-1.hortonworks.com/ has been enabled on all the machines only for a day. I set the 'export http_proxy' and set-up the Ambari server which internally fetched the Oracle 8 JDK. Somehow, 'java -version' still doesn't work, does Ambari really install JDK The Ambari agents will be installed auto. during the cluster install later but then there would be NO Internet connection. How is java(jdk) installed on the other nodes then ? Is it that Ambari pushes the /var/lib/ambari-server/resources/jdk-8u60-linux-x64.tar.gz to all the nodes manually(after all, hadoop would require java) Is it safe to remove the Internet access now

I think that doc. addresses only Ambari installation. Will the HDP installation be hampered in case of a non-root user ? Can the services like HDFS, YARN, Hive execute smoothly if the installation was done via Ambari running as non-root ?

Earlier, on the test machines, I had installed HDP 2.2 using Ambari. I had the root credentials as well as the Internet access. The cluster and the services functioned properly. Now on the prod. machines(4 datanodes + 2 master(HA) + 1 management = 7 machines) and each machine can be allowed to have access only to specific sites. Does this qualify for the 'Temporary Access to Internet' case in the Hortonworks doc. ? Is it possible to provide a complete list of the URLs that need to be accessed for Ambari + HDP Install ?

Earlier, on the test machines, I had installed HDP 2.2 using Ambari. I had the root credentials as well as the Internet access. The cluster and the services functioned properly. Now on the prod. machines(4 datanodes + 2 master(HA) + 1 management = 7 machines) I wish to :
Install Ambari 2.2 on a management node. The Ambari agents will be installed auto.(password-less SSH) Log-in the Ambari mgt. console and install the HDP stack The first challenge is now I don't have the root credentials of any of the machines, I can log-in using my Linux account(connected to an ldap) and install it. As for now, the Internet access is unclear. I read several threads like this and this but I am unsure as to whether I can proceed without root access ? I suspect that non-root user installation will run into issues later, either at the Ambari or the HDP level(or both!). I don't have the liberty of trying out approaches 😞 , hence, I need to be correct till the cluster is installed. How shall I start ?

I have read about the care to be exercised while using ext4 (noatime etc) in several threads but is there some concise guide or doc. which can be used ?

I suspected that the doc. for the file system is merely carried forward from the previous versions, I hope Hortonworks invests some resources in upgrading it 🙂 The LVM part I guess is clear - use it for OS partitions but NOT datanodes, am I right ? Can you help me understand more about your inputs :
XFS is perfectly fine here, so you can let RHEL use the default. However, note that XFS filesystems can not be shrunk, whereas with LVM + ext4, filesystems can be expanded and shrunk while online. This is a big gap for XFS So what should I proceed with - ext4 everywhereORxfs everywhereORboth(xfs for datanodes etc. and ext4 for os partitions or vice versa)
so moving this logging to one of the data disks may be necessary What is the better idea, have large a large, dedicated disk(and add more if required and resize using LVM) for the OS partition so that log, binaries etc. have aplenty space or during the HDP installation itself OR redirect logs(YARN etc.) to some directories on the disks dedicated to the datanode. For example, this is how it is in the test cluster :

Following is the prod. cluster planned infra. Initially 4 data/compute nodes each with 2x12 cores, 256 GB
RAM and 24x2TB disks (plus 2x300 Gb for Linux).3 name/admin nodes (with much less disks configured
as RAID 1). Later, 4-5 datanodes will be added. All nodes will be having RHEL 7. We will be proceeding with the latest 2.4 HDP installation via Ambari. The HDP documentation has following statements : The ext4 file system may have potential data loss
issues with default options because of the "delayed writes" feature.
XFS reportedly also has some data loss issues upon power failure. Do not use
LVM; it adds latency and causes a bottleneck I read several existing threads and doc. but I still don't have a clear understanding of what suits in the latest editions of HDP and RHEL. ext4-vs-xfs-filesystem-survey-of-popularity best-practices-linux-file-systems-for-hdfs any-recommendation-on-how-to-partition-disk-space-1 @Benjamin Leonhardi insightful recommendation Following are the possibilities : Have ext3 on all the partitions on all the nodes Have ext4 on all the partitions on all the nodes Have xfs(default file system for RHEL) on all the partitions on all the nodes Have XFS on the boot disks (and for all disks on the
head/management nodes) e.g: /boot, /var, /usr etc. but use ext3/ext4 on the data disks (that anyhow are
“special” compared to our normal install images) just to minimize risk so good to stick to proposed
standard practices as much as possible Whether LVM should be used for ALL the volumes/partitions OR selectively(use for /var, /usr etc. but NOT for the datanode and log directories) OR don't use it at all Any suggestions/recommendations/further reading(suited to the latest HDP2.4 and RHEL 7 environment) ?

@mlanciaux As mentioned in the original query : DimSnapshot.snapshot_id is the PK of the DimSnapshot table, thus it's count = no. of records in DimSnapshot which is around 8 million I did the following : CREATE TABLE factsamplevalue_snapshot AS SELECT snapshot_id, COUNT(*) FROM factsamplevalue GROUP BY snapshot_id; which resulted into a table with 7914806 rows, sample data : select * from factsamplevalue_snapshot limit 10;
OK
