Programs and Features list
If there is a problem with the installation, the first thing you should do is to go to the
Programs and Features
page
in the Control Panel and check for these two items:
•
Microsoft HDInsight Emulator for Windows Azure
•
Hortonworks Data Platform 1.1 Developer
Uninstall these items, and repeat the installation procedure. The order of uninstall is important. You should
uninstall the
Windows Azure HDInsight Emulator
first, and then the
Hortonworks Data Platform 1.1 Developer
.
The best approach to troubleshoot such installation/uninstallation issues is to enable MSI logging. You can
follow the instructions in the following Knowledge Base article to set up MSI logging:
After enabling logging repeat the action that failed and the log that's generated should point you in the right
direction. If it turns out that uninstallation is failing due to missing setup files then you can probably try to get the
missing files in place from another installation of the emulator.
Just to reiterate, the HDInsight emulator is a single-node deployment. So don't be surprised when you see that
the number of live nodes in your cluster is
1
after you launch the Hadoop Name Node Status portal as shown in
