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

18 hours later I'm down to 6 alerts: Here is the ambari screen shot: That is after I started the Ambari Metrics. It looks like It's some connection errore. For example, here is one ranger alert: Connection failed: [Errno 111] Connection refused to sandbox.hortonworks.com:5151 But if I connect to sandbox.hortonworks.com:5151 with a browser. It works!!! Looks like a dns resolution or a firewall connectivity problem... Is there a way to just reset the alerts? ... View more

Mine doesn't look at all like that!!! Just to be on the safe side! I just re-import the HDP_2.3.2_virtualbox.ova with wirtualbox 4.3.26 I put 4 cpu and 16 gig of ram. I still have problems... Here is the ambari after start: I mean is it me or there shouldn't be any alerts??? That mean when horton saved the VM the alert were there! So I did a yum update on the vm but it's worst ! Here is the ambari after restart: The thing is all these alert make me questioned the accuracy and solidity of the distro. I mean I'm not even shure it's working out of the box! What if I installed something on it and it doesn't work! Is it what I've installed or the Hortonworks environement? I mean this is not right! Am I the only one with these problems? ... P ...

Hi all! I just download the latest sandbox.hortonworks.com HDP 2.3.2 but when started and running for an hour I still have some alerts on the ambari dashboard! Anybody has the same problem? Here are what I can copy from the ambari dashboard: HiveServer2 Process Connection failed on host sandbox.hortonworks.com:10000 (Execution of 'ambari-sudo.sh su ambari-qa -l -s /bin/bash -c 'export PATH='"'"'/usr/sbin:/sbi Hive Metastore Process Metastore on sandbox.hortonworks.com failed (Execution of 'ambari-sudo.sh su ambari-qa -l -s /bin/bash -c 'export PATH='"'"'/usr/sbin:/sbin:/usr/lib/a Ambari There are 21 stale alerts from 1 host(s): History Server RPC Latency, HiveServer2 Process, Ranger Usersync Process, WebHCat Server Status, Ambari Agent Disk Usage, History Server Web UI, App Timeline Web UI, Hive Metastore Process, Atlas Metadata Server Process, History Server CPU Utilization, History Server Process, ResourceManager Web UI, NodeManager Health Summary, ZooKeeper Server Process, ResourceManager CPU Utilization, NodeManager Health, Flume Agent Status, Ranger Admin Process, NodeManager Web UI, ResourceManager RPC Latency, Metadata Server Web UI CRIT for about an hour There are 21 stale alerts from 1 host(s): History Server RPC Latency, I don't understand why the vm has multiples alerts out of the box!

After some research I was able to have the VM work for more than 12 hours now. Looks like virtualbox 5 has some new features regarding clock. 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 don't think it's related to cpu assignment, The vm has 4 cpu @ 100% cap. And doing nothing. The load is below 0.3 most of the time. As for the kernel! The host has latest current kernel Linux host 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux And the known issue is related for kernel in lucid-updates not LTS 14.04 Thanks for the suggestions. ...
