Failed Cluster Installation on Initial Hadoop Cluster Installation via Cloudera Manager

At this point I think you may be able to start a new cluster installation from a fresh Cloudera Manager install: http://192.168.1.201:7180/cmf/express-wizard/. I’m not sure about that, but I’ll update later if it is indeed the case.


BTW, the “Abort Installation” button on the Cluster Installation (step 3) applies to hosts whose installation has NOT completed successfully. It won’t roll back all your hosts, in the case where just one host is unhappy for some reason. I’ve seen a fairly regular occurrence of just one host having some intermittent network problem for example, that results in the express-wizard getting hung up waiting on that machine, but that machine doesn’t know to tell the wizard anything. So you could be sitting there forever. In that case, just click that “Abort Installation” button. You should then see buttons replace it about rolling back failed hosts and then attempt reinstall on failed hosts.
