Does anyone know how to find a Cloudera road map for releases for all services and components for CDH? I can see here https://www.cloudera.com/documentation/enterprise/release-notes/topics/impala_incompatible_changes.html#incompatible_changes_28x a lot of stuff about Impala w.r.t. to CDH 5.10 and I can see in the repository https://repository.cloudera.com/cloudera/cloudera-repos/com/cloudera/cdh/cdh-root/5.10.0-SNAPSHOT/ that CDH 5.10 had additions on Nov 28. How can I find when CDH 5.10 will be released or when it is planned to be released, the next minor version the same thing, etc. But they don't talk about it in the official notes here http://www.cloudera.com/documentation/enterprise/release-notes/topics/rn_consolidated_pcm.html. I'm hoping there is some insight into this somewhere on the net?
Cloudera releases a new CDH 5.X.0 release approximately every 3 months. By taking a look at the dates of previous releases you can have a fair idea on when to expect the next one.
According to http://archive.cloudera.com/cdh5/parcels/, CDH 5.9.0 became available on 21 of October. So I would expect the 5.10 in the end of January, 2017.

Is there a file which ties the libversion to the release number. The libversion is in a file in the release, but I can't find documentation to trace this back. Working with a version of Linux that has one libversion of Poco and a SDK that was released was a different libversion and I am trying to track down the releases. Thanks.
I figured I go ahead and try to get and answer on Git Hub. There is no master file/database with the numbers , but it isn't super difficult to find. If you go to the tagged version (eg 1.11.0) and look at libversion - the number will be 81. Go back to tag version 1.6.1 and the libversion and the number is 31. I was able to create the database of the versions I needed based on trial and error.
I am not able to locate any docs to upgrade unmanaged cluster (running 5.16) via command line like the one below for 5.15
https://www.cloudera.com/documentation/enterprise/5-15-x/topics/cdh_ig_upgrade_command_line.html
Can someone point me to the corresponding doc for 6.1 ?
This has been answered in cloudera forum. Cross-posting to prevent link rot
You can upgrade the packages based cluster but it's very tedious
process so not recommended.
https://docs.cloudera.com/documentation/enterprise/upgrade/topics/ug_overview.html
The best way is to migrate from packages to parcels and then
upgrade.
https://docs.cloudera.com/documentation/enterprise/6/latest/topics/cm_ig_migrating_packages_to_parce...
Once you migrated you can use this page to get the CM server running
with Web UI.
https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/installation.html
Regarding your ask "Is there any way by which an Unmanaged 5.x
cluster can move to CDH 6.x (may be adding it in Cloudera Manager
and then moving to 6.x)?"
I am thinking that you can build a 1 node CM server and then add these
present cluster by adding node in that CM. (Though I haven't tried
this on packages)
I have Artifactory 5.4 running and would like to upgrade it to the latest available one: 6.3.3. Do I need to upgrade it to some interim version or can I go straight to 6.3.3 ?
You should be able to upgrade from version 5 to 6 without the need for an interim version.
Before doing so, however, it is strongly suggested that you
Do a complete system export. If at any time you decide to roll back to the older version, you can use the export to reproduce the system in its entirety.
Backup your database.
I am upgrading CentOS 5.6 to CentOS 6.4, can anyone give me the differentiating points or a link to a website that shows that
The entire release history is at http://wiki.centos.org/Manuals/ReleaseNotes
You will need to read/combine the release notes for 5.7..5.10 & 6.0..6.4 and you may also need to take a look at the bug tracker.
It's a major upgrade from 5 to 6 so the list of differences is long and it's dedicated multiple webpages to the changes in doing that, just google "centos migrate 5 to 6" and you get a ton of hits.
Redhats planning guide at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/pdf/Migration_Planning_Guide/Red_Hat_Enterprise_Linux-6-Migration_Planning_Guide-en-US.pdf is one that points out differences and what you need to plan for.
I am deploying a large set of perl/shell/sql code on AIX. these could be (and are) different applications with their own dev teams, source control repos, etc.
I am lazy and want to make deployments/roll-backs easier - and I am digging towards rpm packaging with all it's +/- benefits.
AIX native system of packaging is installp (with bff files).
am I on a right track with rpm? oss4aix.org uses rpm FWIW.
any input/best practices is appreciated.
thanks
"installp" is a bit of a black art. For a long time it was impossible to get the build software without spending non trivial amounts of money so very few people outside IBM (and Bull) bothered with it.
"rpm" on the other hand has been freely available for years. For scripty type stuff there should be no special considerations for AIX so the large body of experience, knowledge and example code available for Linux will be useful to you.
I dont think IBM is dropping AIX anytime soon, but, they are actively porting the standard linux tools to AIX and some of the AIX tools to Linux so the environments are converging. I think its only a matter of time before installp become "depreciated" in favour of rpm.
I never had to develop instalp packages. I am under the impression that IBM is going to buy a major Linux distribution and stop all their proprietary business sometime soon. I think for the long term moving to rpm is getting ahead of the curve.
I found one document to build rpm 5.0 and yum on AIX.

Aix 4,5,6 use the RPM v3.0 - 1998 circa, iirc RedHat 6.2. A zillion of resolved bugs and new functionality are in rpm nowdays. So use it but don't aspect that you can do with it what other do in a moderm linux rpm distro.
Or, as a good alternative to build yourself rpm 5 - which other on aix ? - try
openpkg http://www.openpkg.org/
Have a look at the polypkg tool we wrote; it's a shell script that does the hard work of making packages for you.
