Today I spoke with Robert Molina from Hortonworks and possibly found what is creating all those alerts! The sandbox is intended to be run on a desktop with a NAT networked interface. I set it up on a dedicaded headless server with a bridge adaptor. Looks like sandbox have a problem with that and that cause some of the services configs to not function properly! As a result some services works but reports network connections alerts! After some config change. The related alerts weren't there anymore. So always use a vm for and how it was intended to be used. Thanks to the hortonworks team and Robert who wanted to go to the bottom of this. Conclusion: If you want, like me, to test drive hortonworks on a headless server. Start from scratch and build it! What every sysadmin should do anyways... That's what I'll do this week end... P ... View more

Here is my fix: <code>I added grub arguments on the kernel clock=pit nosmp noapic nolapic in order to have clocksource=kvm-clock Look to check clocksouce: Check what clocksource that you are using: <code>$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource Check which ones that are available: <code>$ cat /sys/devices/system/clocksource/clocksource0/available_clocksource If you got a "kvm-clock" entry in "available_clocksource" try to use it by setting kernel parameter: <code>clocksource=kvm-clock From http://serverfault.com/questions/132197/best-pract...

I also get this warning on HDP 2.3.2 - It is only a warning and I'd be interested to know what the impact is. It seems strange that the "ranger" user doesn't have access to the "/var/lib/ranger" folder...especially as there are .bash_profile files in here, suggesting it's some kind of home folder [root@sandbox ranger]# id ranger uid=1008(ranger) gid=503(hadoop) groups=503(hadoop),487(ranger) [root@sandbox ranger]# ls -dl /var/lib/ranger drwx------ 2 kms kms 4096 2015-10-27 12:56 /var/lib/ranger [root@sandbox ranger]# ls -la . total 20 drwx------ 2 kms kms 4096 2015-10-27 12:56 . drwxr-xr-x. 39 root root 4096 2016-02-28 14:38 .. -rw-r--r-- 1 kms kms 18 2015-09-22 16:40 .bash_logout -rw-r--r-- 1 kms kms 176 2015-09-22 16:40 .bash_profile -rw-r--r-- 1 kms kms 124 2015-09-22 16:40 .bashrc [root@sandbox ranger]# getent passwd ranger ranger:x:1008:503:Ranger:/var/lib/ranger:/bin/bash [root@sandbox ranger]# Should I make the 'ranger' user part of the kms group? I would still have to make the /var/lib/ranger folder group readable (at least). ... View more
