[jira] [Commented] (IGNITE-14750) NullPointerException when
starting MaintenanceProcessor after upgrade from 2.9
[ https://issues.apache.org/jira/browse/IGNITE-14750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17348560#comment-17348560 ]
Stephen Darlington commented on IGNITE-14750:
---------------------------------------------
Basically, [this code|https://github.com/apache/ignite/blob/22af51e366acb4721122fec4249fac215234dd42/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/persistence/filename/PdsConsistentIdProcessor.java#L246] assumes that a path is a directory based on the result of a predicate... but it turns out to be a file. I'm not clear how this could happen – and the files have now been deleted – but the cause is clear

> Upgrading from Ignite 2.9 to 2.10, using persistence we got the following error on one node. The other nodes started correctly. Ended up deleting the persistence store and creating a new node.
