[jira] [Commented] (HDDS-5525) Datanode snapshot can be installed while pre-finalize actions are running

    [ https://issues.apache.org/jira/browse/HDDS-5525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17475760#comment-17475760 ] 

Ethan Rose commented on HDDS-5525:
----------------------------------

Removing 1.3.0 target version since 1.3.0 has no planned HDDS upgrade layout features. The current solution implemented in HDDS-5513 will continue to work until an HDDS layout feature needs to run pre-finalize actions on container data.

> In HDDS-5513, a race condition occurred because snapshot installation was occurring before the main DatanodeStateMachine loop, and therefore occurring while pre-finalize actions could be running. In that Jira a workaround was implemented to unblock upgrades, but this will pose a problem if we need to run pre-finalize actions involving container data in the future.
