[jira] [Resolved] (HDDS-7089) Intermittent failure in freon data validation after datanode restart in Kubernetes test
[ https://issues.apache.org/jira/browse/HDDS-7089?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Attila Doroszlai resolved HDDS-7089.
------------------------------------
Fix Version/s: 1.4.0
Resolution: Fixed
The problem was that after pipeline refresh the client ({{BlockInputStream}}) gave up, although SCM returned the datanodes with updated IP address. Datanode equality ignores address, only compares UUIDs.
This seems to be working fine after HDDS-7231, which removed the {{sameDatanodes}} check after pipeline refresh.
