Hi Yuci, Basically, this error means that affinity function on node A gave node B as a primary node for a key. Node A than sent a request to node B, but affinity on node B doesn't think that this key belong locally. In other words, affinity function worked inconsistently on different nodes.
Usually this is caused by incorrect hashCode() implementation of the key class (as pointed out in the message). Unfortunately, the key itself is not printed out, so I would recommend to put a breakpoint and go back through the trace to see for which key the partition number is calculated incorrectly. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Failed-to-process-message-Creating-partition-which-does-not-belong-to-local-node-tp9332p9341.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
