I went through the upgrade procedure on Wed the 9th to upgrade our Cloudera Manager managed cluster from 5.4.9 up to the 5.5.X version. I had originally intended to go to 5.5.1 but when I started the process I realized that 5.5.2 was available. I first upgraded our Cloudera Manager install to that and then all the agents and finally upgraded the whole cluster to CDH5.5.2. Everything looks to be working properly after upgrade however when I went to add new nodes to the cluster yesterday I found that the debian repository for 5.5.2 wasn't available anymore and I couldn't add any new nodes. I tried pointing to just the 5.5 repository but it was complaining that the agent install wasn't the correct version.   Was CDH5.5.2 pulled? If so what is the recommended course of action I should take on our cluster? CDH5.5.1 parcel is available in cloudera manager for me to "upgrade" to but I wanted to confirm that it would be ok to take that route. Also should I be downgrading Cloudera Manager and all the agents? What's the correct course of action for that piece?   The only reference I can find to CDH5.5.2 release now is this google groups post stating its release: https://groups.google.com/a/cloudera.org/forum/#!topic/cdh-user/a9ANiqPNVw8 All the documentation links are now gone as well as all the debian repositories. ...
