Datastax Enterprise 5.0 Lifecycle Manager - provis

问题:

I'm trying to install Datastax Enterprise 5.0 by using Lifecycle Manager (I've installed Opscenter). But install job fails with a message that is not too descriptive, and obviously pretty rare (0 hits in Google):

Event Type:

error-MeldError

Result/Message:

Meld failed on: name="<nodename>" ssh-management-address="<nodeip>" node-id="<someguid>" job-id="<someguid>" stdout="" stderr=""

Stack trace:

Any ideas?

Thanks!
