-----------------------------------------------
Summary: SCM container placement policies should check for
duplicate hostnames while allocating pipelines
Key: HDDS-11670
URL: https://issues.apache.org/jira/browse/HDDS-11670
Project: Apache Ozone
Issue Type: Task
Components: SCM
Reporter: Swaminathan Balachandran
Assignee: Swaminathan Balachandran
SCM container placement policies should check for duplicate hostnames while
allocating pipelines. This can happen when a volume containing datanode.id.dir
fails and reinitializes the datanode on restart. This could lead to SCM
containing 2 nodes with the same ip & hostname but different datanode.id. This
can happen because datanode.id is the primary identifier of a datanode in SCM.
On pipeline allocation there is a possiblity of these 2 nodes getting picked up
in a timeframe where the old node has not been marked dead and the new node has
been registered.
