1) Yes, that is normal. You have to manually finalize the upgrade. 2) Probably, because (as I understand it), it keeps a backup of the pre-upgraded state. 3) you can use hadoop dfsadmin -finalizeUpgrade to finalize it. See here: http://wiki.apache.org/hadoop/Hadoop_Upgrade 4) I assume the finalizeUpgrade command will do that for you.
