Jeff Storck updated NIFI-5585: ------------------------------ Status: Patch Available (was: In Progress) WIP Apache NiFi [PR 3010|https://github.com/apache/nifi/pull/3010] > Decommision Nodes from Cluster > ------------------------------ > > Key: NIFI-5585 > URL: https://issues.apache.org/jira/browse/NIFI-5585 > Project: Apache NiFi > Issue Type: Improvement > Components: Core Framework > Affects Versions: 1.7.1 > Reporter: Jeff Storck > Assignee: Jeff Storck > Priority: Major > > Allow a node in the cluster to be decommissioned, rebalancing flowfiles on > the node to be decommissioned to the other active nodes. This work depends > on NIFI-5516. > Similar to the client sending PUT request a DISCONNECTING message to > cluster/nodes/\{id}, a DECOMMISSIONING message can be sent as a PUT request > to the same URI to initiate a DECOMMISSION for a DISCONNECTED node. The > DECOMMISSIONING request will be idempotent. > The steps to decommission a node and remove it from the cluster are: > # Send request to disconnect the node > # Once disconnect completes, send request to decommission the node. > # Once decommission completes, send request to delete node. > When an error occurs and the node can not complete decommissioning, the user > can: > # Send request to delete the node from the cluster > # Diagnose why the node had issues with the decommission (out of memory, no > network connection, etc) and address the issue > # Restart NiFi on the node to so that it will reconnect to the cluster > # Go through the steps to decommission and remove a node -- This message was sent by Atlassian JIRA (v7.6.3#76005)
