Junping Du created HADOOP-8304: ---------------------------------- Summary: DNSToSwitchMapping should add interface to resolve individual host besides a list of host Key: HADOOP-8304 URL: https://issues.apache.org/jira/browse/HADOOP-8304 Project: Hadoop Common Issue Type: Improvement Components: io Affects Versions: 1.0.0, 2.0.0 Reporter: Junping Du Assignee: Junping Du Fix For: 2.0.0
DNSToSwitchMapping now has only one API to resolve a host list: public List<String> resolve(List<String> names). But the two major caller: RackResolver.resolve() and DatanodeManager.resolveNetworkLocation() are taking single host name but have to wrapper it to an single entry ArrayList. This is not necessary especially the host has been cached before. -- This message is automatically generated by JIRA.
