(Updated Aug. 25, 2016, 12:44 p.m.) Review request for Ambari, Alejandro Fernandez, Nate Cole, and Sebastian Toader. Bugs: AMBARI-18262 https://issues.apache.org/jira/browse/AMBARI-18262 Repository: ambari Description ------- Caused by: AMBARI-18240, in enable namenode HA wizard, failure happened at "Start Additional NameNode" step. The new logic from AMBARI-18240 assumed only 1 entry for active and standby. Since both NNs were "standby" it was only returning a tuple with the first NN in it. We should not be assuming [0] and instead be iterating over the tuple. Diffs (updated) ----- ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/hdfs_namenode.py 63d72aa ambari-server/src/test/python/stacks/2.0.6/HDFS/test_namenode.py f3c657e Diff: https://reviews.apache.org/r/51430/diff/ Testing (updated) ------- Verified the UI Wizard completes now. ---------------------------------------------------------------------- Total run:1124 Total errors:0 Total failures:0 OK Thanks, Jonathan Hurley
