The Scary DBA

I have twenty+ years experience in IT. That time was spent in technical support, development and database administration. I work forRed Gate Software as a Product Evangelist. I write articles for publication at SQL Server Central, Simple-Talk, PASS Book Reviews and SQL Server Standard. I have published two books, ”Understanding SQL Server Execution Plans” and “SQL Server 2008 Query Performance Tuning Distilled.” I’m one of the founding officers of the Southern New England SQL Server Users Group and its current president. I also work on part-time, short-term, off-site consulting contracts. In 2009 and 2010 I was awarded as a Microsoft SQL Server MVP. In the past I’ve been called rough, intimidating and scary. To which I usually reply, “Good.” You can contact me through grant -at- scarydba dot kom (unobfuscate as necessary).

HDInsight: Trying again

And I thought this would be so easy.

Latest attempt. I just did an uninstall of HDInsight. Then I found all the Hadoop folders on the drive and removed them. I validated that there were no services left running or anything else that might interfere with a fresh install. Then, I rebooted the server (have you tried turning it off and on again?). After all that, I tried rerunning the HDInsight Community Preview. This time I ran it as an administrator on the system, even though I already am logged in as one. Paranoia at every step is my new approach since there have been no errors until I try to turn the silly thing on.

And the install went perfectly. I can see two folders, Hadoop and HadoopFeaturePackSetup. Last time there was a third folder HadoopInstall or something like that. This doesn’t bode well. Let me check the services. Nope. I can’t see anything added. Crud. So, I try the powershell command anyway, just to see what I’ll get. It’s a new error, which is nice:

Join-Path : Cannot bind argument to parameter ‘Path’ because it is null.
At C:\hadoop\start-onebox.ps1:2 char:23
+ $start_cmd = Join-Path <<<< $env:ISOTOPEJS_HOME “bin/start_daemons.cmd”;
+ CategoryInfo : InvalidData: (:) [Join-Path], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.JoinPathCom
mand

Crud. My assumption is, I’m doing something wrong. I just can’t figure out what. Lots of searching later, I think I may have found the issue. I’ve been trying to install this on my local server that I use for lots of my tests because it’s a physical box that I can access on the road. It’s also a domain controller. I finally tracked down this thread on Microsoft’s forums. Great. OK. Next step, setting up a virtual server. May as well make it Windows 2012 while I’m at it. More to come when I get past this hurdle. Oy.
