[jira] [Created] (HDDS-2626) Avoid hostname lookup for invalid
local IP addresses
Attila Doroszlai created HDDS-2626:
--------------------------------------
Summary: Avoid hostname lookup for invalid local IP addresses
Key: HDDS-2626
URL: https://issues.apache.org/jira/browse/HDDS-2626
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
{{OzoneSecurityUtil#getValidInetsForCurrentHost}} performs hostname lookup for all local network interfaces, even for invalid addresses. This significantly slows down some secure tests ({{TestHddsSecureDatanodeInit}}, {{TestSecureOzoneCluster}}) when run on a machine with special IPv6 network interfaces due to timeout reaching IPv6 DNS servers.
This issue proposes to disable the lookup for invalid addresses.
