> STR:
> 1. User registers repo version 2.3.0.0 (notice that a build number was not provided), and clicks the Install button
> 2. On all of the hosts, the yum commands timeout (or does a partial install), this way, "hdp-select versions" will report that 2 versions exist (2.2.0.0-2041 and 2.3.0.0-2800). Because the install did not succeed, the command will not return the actual_version installed (which was 2.3.0.0-2800). Note: I did this by decreasing the timeouts in ambari.properties file to 5 mins, and adding a sleep in install_packages.py after the first package was installed.
> 3. The ambari server code then changes the state of the 2.3.0.0 version it knows about to INSTALL_FAILED so that the user can retry, but did not update the repo version with the actual build version that includes the build number.
> 4. User retries and this time it succeeds. However, the delta of "hdp-select versions" outputs "", so no "actual_version" is returned! This is really bad because the build number is needed for ambari to use it whenever it calls "hdp-select set <comp> <version>"
> 5. The ambari server code will change the state to INSTALLED.
> The fix is for install_packages.py to always return the actual_version (even in the case of a failure) so that Ambari server can correct the database entry (even if the command fails/timesout). This will only happen the first time, but subsequent attempts to retry installation will use the right value so an exact match will be found in the database.
