Summary: Initial PME hangs because of multiple blinking nodes Key: IGNITE-13374 URL: https://issues.apache.org/jira/browse/IGNITE-13374 Project: Ignite Issue Type: Bug Reporter: Alexander Lapin Assignee: Alexander Lapin Fix For: 2.10 *Root cause* of the issue is a race inside GridDhtPartitionsExchangeFuture on client side between two processes: # When old coordinator fails and the new one takes over it sends GridDhtPartitionsSingleRequest messages to all nodes including clients to restore exchange results. Processing this message on client includes updating current coordinator reference (crd field). # When future receives discovery notification about old coordinator failure it should detect change of coordinator and send GridDhtPartitionsSingleMessage to new coordinator to obtain affinity. But updated crd field prevents client from detecting coordinator failure and sending SingleMessage to new coordinator which in turn leads to hanging client. -- This message was sent by Atlassian Jira (v8.3.4#803005)
