I'm new to Cloudera Administration. But I learned about Cloudera Administration somewhat with the help of Cloudera Documentation. I have created
Cloudera 3 node cluster(Ubuntu) already. Now I'm trying to create a 3 node cluster(RedHat) with the same Cloudera Manager. Whe I start the process of installation,
everything is fine. But during distributing the parcels from existing cluster, the process gets stopped. So anyone please help me, How to distribute the parcels from
existing cluster to new cluster. I'm using CDH version 5.4.0. Is this possible?
Cloudera Manager will detect the variation and download and distribute the parcel for that target server's OS release.
This functionality is included to provide for flexibilty and support migrations and upgrades of cluster servers.
We do not reccomend remaining in a mixed release topology however for an extended period, and to
use the fucntionality as a transitional deployment model, only.
This sounds more like you have issues accessing the repo's then, rather than something internal to CM.
You MUST be on supported OS release for this to work as well... see the following URL
You would add a new host to the cluster, and following that process it would deploy the agent to the host
( unless you pre-installed the CM agent on the new host and configured it manually then it would "just show up"
in the add new host UI on the second tab)
What linux distribution / versions are in use in your cluster.
Realize you can not import an existing cluster into a CM install, this is discussed within the community
boards a number of times at this point. You can use the CM API to define your new cluster, as well.
If your adding new hosts and extending your existing cluster with a different supported release, this will work.
If you are using CM to manage a cluster of one OS type, and then you make a second cluster of another OS type within
CM by adding the hosts and allowing it to deploy the CDH parcel across that cluster... that will work too.
What won't work is trying to add a CDH only cluster to CM for management. CM must build the cluster to be able to manage it.
Also, use the "host inspector" to make sure you have no obvious issues with the hosts that are part of the second cluster. Run the hosts inspector from the hosts section of the CM UI, and the look at the report, note that the > can be clicked next to any of the items with alerts, to display the detail of the inspector for that item.
