Description

When a node is decommissioned, allocation tags that are attached to the node are not removed.
I could see that allocation tags are revived when recommissioning the node.

RM removes allocation tags only if NM confirms the container releases by YARN-8511. but, decommissioned NM does not connect to RM anymore.
Once a node is decommissioned, allocation tags that attached to the node should be removed immediately.
