Firstly let me apologize for not getting back to you sooner on this. You are correct that rpm is expecting a package name. You can find the package name with “rpm -qa | grep oozie”. The instructions should have pointed this out. There is also a typo in what is there, a ‘-‘ is missing between oozie and $old_version_number. Thanks for bringing these to our attention, I’ll log a bug about them so that they will be fixed. As far as the estimation on the time goes though it is quite difficult to come up with one, as there are a large number of variables that can cause it to vary greatly. Such as the number of computer in the cluster, the speed of the network, the speed of the computers and many more.
