Alejandro Fernandez reassigned AMBARI-13424: -------------------------------------------- Assignee: Alejandro Fernandez > preUpgradeCheck setting ineffective for NNHA in Ambari 2.1.2 > ------------------------------------------------------------ > > Key: AMBARI-13424 > URL: https://issues.apache.org/jira/browse/AMBARI-13424 > Project: Ambari > Issue Type: Bug > Components: ambari-web > Affects Versions: 2.1.2 > Environment: Ambari 2.1.2, upgrading HDP 2.2.8 to 2.3.0.0. > Single CentOS VM running Ambari Server and Ambari Agent 2.1.2, and HDP. > Only hdfs, zookeeper and ambari metrics components are installed. > The cluster has no NameNode HA enabled. > Reporter: Robert Ketcherside > Assignee: Alejandro Fernandez > > If the user disables preUpgradeCheck from the Experimental settings page, and > then presses the "Perform Upgrade" button, they are immediately prompted with > a preupgradecheck error, rather than proress of upgrade of HDFS. On Ambari > 2.1.1, upgrade commenced and proceeded until the HDFS component itself > encountered an error during upgrade. > This blocks rolling upgrade with Isilon. NameNode HA is not relevant. If the > preupgradecheck is ignored with Isilon, upgrade should commence and then the > HDFS upgrade step will complete. (eg, 2.1.0, 2.1.1.) > Here is the text within the box that appears (remember, this is with > preUpgradeCheck disabled). > Error > 500 status code received on POST method for API: > /api/v1/clusters/Hello/upgrades > Error message: An internal system exception occurred: Unable to perform > upgrade.
