Hi Alper, This is caused because of race. NPE happens between two events: removing affinity nodes and change cache state to STOPPED. In other words: 1. Remove affinity nodes; -- Start scan query. 2. Start exchange; 3. Change cache state.
I've opened a ticket for that [1]. [1] https://issues.apache.org/jira/browse/IGNITE-4487 Thanks! -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/NullPointerException-on-ScanQuery-tp9413p9717.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
