> ambari-server-2.1.0-1462.x86_64
> Attempting to register and install a repo version was stuck on one of the
> hosts.
> The cluster version was stuck in INSTALLING, and so was one of the hosts; the
> other hosts were fine
> Log from host were it failed
> {code}
> 2015-09-03 12:21:59,319 - Attempting to determine actual version with build
> number.
> 2015-09-03 12:21:59,319 - Old versions: ['2.3.2.0-2598', '2.3.2.0-2716']
> 2015-09-03 12:21:59,369 - New versions: ['2.3.2.0-2598', '2.3.2.0-2716']
> 2015-09-03 12:21:59,369 - Deltas: set([])
> 2015-09-03 12:21:59,370 - Cannot determine a new actual version installed by
> using the delta method.
> 2015-09-03 12:21:59,370 - Found actual version 2.3.2.0-210 by parsing file
> /var/lib/ambari-agent/data/repo_version_history.csv
> {code}
> In fact, the bug (at least at branch-2.1.0) is that we can not overwrite old
> build version of the same stack. For example,
> {code}
> >>> import repo_version_history
> >>> import logging
> >>> Logger = logging.getLogger()
> >>> global Logger
> >>> repo_version_history.write_actual_version_to_history_file('2.3.2.0',
> >>> '2.3.2.0-210')
> False
> >>> repo_version_history.write_actual_version_to_history_file('2.3.2.0',
> >>> '2.3.2.0-2716')
> False
> {code}
> produces
> {code}
> cat /tmp/repo_version_history.csv
> 2.3.2.0,2.3.2.0-210
> {code}
> Originally check for existing repo version was added to avoid appending the
> same repo version multiple times to file. But later we decided to consider
> only "normalized" repo version (without build number) and introduced not
> obvious bug
> So the bug STR is to:
> - successfully install first repo version on host
> - install second repo version (of the same stack) on host, and it should fail
> during installation.
