Are you able to provide the following listing from the CM host please:
# ls -l /opt/cloudera/parcel*

See below.
The error appears during the wizard before the parcels have been selected. Although previously when I installed using the package approach I got as far as completing the wizard and then the error appeared when logging into CM for the first time.
The build is CM 5.2.1 on CentOS 6.3.
Thanks

Here is the listing from my host. This is a worker node but should look similar on the Cloudera Manager host as well

The exception you're seeing is due to the parse of a parcel name failing. The format should be like in the listing above whereas in your cluster it is just "CDH" which should ideally be a symlink, not a directory.

Are you aware if the contents in these directories was manually changed sometime?

That CM folder contained by the looks of things an old Spark parcel from a previous failed install.
Removing the CM folder (in fact the /opt/cloudera/ folder in its entirety) and removing and reinstalling cloudera-scm-manager seems to have resolved the issue.
It would be nice to see this error handled better so it doesn't bring back the endless pop ups. And maybe the documentation updated if that folder does need to be empty prior to a new installation.
Thanks

Your point is taken. I will file an internal jira to track this error as it is confusing. The error message itself could use some improvement.
