Josh Elser reassigned ACCUMULO-3958: ------------------------------------ Assignee: Josh Elser > Monitor.fetchData should check for null instance name > ----------------------------------------------------- > > Key: ACCUMULO-3958 > URL: https://issues.apache.org/jira/browse/ACCUMULO-3958 > Project: Accumulo > Issue Type: Bug > Components: monitor > Reporter: Josh Elser > Assignee: Josh Elser > Priority: Minor > Fix For: 1.6.4, 1.7.1, 1.8.0 > > > Had an odd situation where the monitor would throw an NPE constantly when I > tried to view any page. > It was throwing a NPE trying to accessed the cached instance name. It appears > that {{HdfsZooInstance.getInstance().getInstanceName(}} may return null, but > the monitor code is not written to account for that. > The monitor should check for null values before setting the instance name > into {{cachedInstanceName}}. When the instance name is null, it should > reschedule the timertask to try to fetch a (non-null) instance name. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
