So there I was, casually working away on my HDInsight sessions for a conference next week. Happily submitting my jars and watching my map reduce jobs running, like a happy little data scientist. I had just finished writing my umpteenth job and I wanted to submit it, so I clicked to open the HDInsight dashboard; but it failed to open, reporting that there was nothing on the end of localhost:8085. Hmm, odd. so I opened the job tracker: dead too, and so was the namenode.
I opened the services manager under Windows and saw that, although all the Hadoop services were marked as automatic they were all stopped. Weird, but okay. I clicked to start the first one and it failed to start, reporting a logon failure. “Well that’s nonsense” thinks I, but I’ve not got time to fix that, I’ll just reinstall.
So I uninstalled HDInsight dev preview and the HDP, then fired up Web Platform Installer and reinstalled it. Job done. Well, not quite, because although the namenode and jobtracker and the command line shortcuts installed okay the dashboard was missing. Since I knew the URL I just added it and click to launch it:
But no, the dashboard hadn’t been installed. Weird, but not to worry, so I Googled it with Bing, or I might have Binged it with Google, I can’t really remember, but the upshot was that I found this post:
Which basically said I had to had go here:
and hack the package. So I went there and low!
The package isn’t there. So, that’ll explain why it didn’t install, but doesn’t explain why it hasn’t been downloaded, nor why HDInsight suddenly stopped working in the first place, after having been happily mapping and reducing it’s little heart out for weeks.
If I get to the bottom of it I’ll let you know.
