Koji Kawamura updated NIFI-5849: -------------------------------- Status: Patch Available (was: In Progress) > ListSFTP, ListFTP processors lose Cluster state on restart. > ----------------------------------------------------------- > > Key: NIFI-5849 > URL: https://issues.apache.org/jira/browse/NIFI-5849 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.8.0 > Reporter: Truong Duc Kien > Assignee: Koji Kawamura > Priority: Critical > > In a cluster environment, restarting a processor that extends > {{AbstractListProcessor}} could lead to the erasure of that processor's > existing cluster states. > This bug was introduced in commit > [https://github.com/apache/nifi/commit/8b9d4461185848fd552a639ac14b7926164d5426] > . > Before that commit, the {{resetState}} variable is changed to false after the > state is clear, inside {{updateState}} method. However, the commit moved this > line to inside the {{onTrigger}} method. This is problematic, because > {{onTrigger}} method is only called on the primary node. As a result, the > {{resetState}} variable is only reset to false on primary node, but not on > the other nodes. When the user restarts the processor, every nodes will > re-execute the {{updateState}} method and the Cluster state will be cleared. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
