(Updated June 13, 2016, 9:22 a.m.) Review request for Ambari, Andrew Onischuk, Jayush Luniya, Sandor Magyari, Sumit Mohanty, and Sebastian Toader. Changes ------- Added Jayush. Bugs: AMBARI-16952 https://issues.apache.org/jira/browse/AMBARI-16952 Repository: ambari Description (updated) ------- In case the hdp-select command fails during a service / component installation there's no contextual information about the cause of the failure. This issue is for logging information about the machine on which the hdp-select command fails. This solution wraps hdp-select command calls in a try/catch block and logs failure / hdp installation related information. The patch only applies for 2.2-next versions. Based on the git logs the affected codebase has been refactored as part of AMBARI-15329. (This addition should be ported to the newer versions isf applicable) Diffs ----- ambari-common/src/main/python/resource_management/libraries/functions/hdp_select.py 9a3201e Diff: https://reviews.apache.org/r/48044/diff/ Testing ------- Unit tests passed. Thanks, Laszlo Puskas
