Dr. Martin Menzel commented on HADOOP-3619: ------------------------------------------- The test org.apache.hadoop.metrics2.impl.TestMetricsSystemImpl doesn't fail on my system. One of my testcases checks a DNS server entry of a.nic.de. Is it possible that the Jenkins system is not able to resolve external / internet addresses? > DNS.getHosts triggers an ArrayIndexOutOfBoundsException in reverseDNS if one > of the interfaces is IPv6 > ------------------------------------------------------------------------------------------------------ > > Key: HADOOP-3619 > URL: https://issues.apache.org/jira/browse/HADOOP-3619 > Project: Hadoop Common > Issue Type: Bug > Reporter: Steve Loughran > Labels: patch > Attachments: HADOOP-3619.patch > > > reverseDNS tries to split a host address string by ".", and so fails if ":" > is the separator, as it is in IPv6. When it tries to access the parts of the > address, a stack trace is seen. -- This message was sent by Atlassian JIRA (v6.2#6252)
