What version of CM/CDH are you using? Do you have an enterprise licensee (its required for Auto-TLS).   From the documentation here:    https://www.cloudera.com/documentation/enterprise/latest/topics/auto_tls.html   What section/step of the documentation are you on?    All that step did (touching the database) was disable TLS in the CM config...  ...

Our documentation clearly states we support MySQL, PostGres and Oracle for the majority of the runtime databases used by the platform.   Please see the following discussion:   For CM database requirements: http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_cm_requirements.html#cmig_topic_4_4_unique_1   For CDH database requirements: http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_ig_req_supported_versions.html#topic_2_unique_5 ...

Actually, by design, its meant to operate that way.  All cluster nodes must be at the same release level, and this is verified on startup.  What you did was pull the resources out from under the database and trigger a server service halt because it could not audit deployed vs staged parcels.  If we threw away the CDH parcel, how would you add servers and additional cluster service role instances?  Cloudera Manager can manage multiple CDH clusters that may at be varying release levels too.    We go through the disk requirements here:  http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_reqs_space.html   The cluster maintains parcel deployment based on the UI within the CM server, you can not manage these from the command line (by doing something like removing the files from the path).  If there are additional/old unused parces you can remove them using the parcel management screen.   http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_parcels.html   You can get the CM server down to where its only storing the current parcel in its repo, using the UI. Having Cloudera Manager on a CDH cluster node will drive your storage issues as well.           ... View more

  1. If I am to use a local repository of parcels for a cluster connected to the internet. Will couldera manager still be able to detect if new parcels are available? And can I elect to not upgrade?   Yes the parcels would just appear as available parcels, you pick what to download   The overview is here: http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_parcels.html   This goes into how to create a local parcel repository    http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_create_local_parcel_repo.html     2. Can I successfully rebuild a cluster using older versions of parcels from a local repository that I might have downloaded previously?   You could rebuild a cluster from scratch and then import data in yes, you could not reliably back-rev a deployment into a previous parcel version and expect things to work.  But that is an issue with package based installations as well and not unique to parcels.     ...
