Summary: Re-balancing is cancelled if client node joins Key: IGNITE-7165 URL: https://issues.apache.org/jira/browse/IGNITE-7165 Project: Ignite Issue Type: Bug Reporter: Mikhail Cherkasov Assignee: Anton Vinogradov Priority: Critical Re-balancing is canceled if client node joins. Re-balancing can take hours and each time when client node joins it starts again: [15:10:05,700][INFO][disco-event-worker-#61%statement_grid%][GridDiscoveryManager] Added new node to topology: TcpDiscoveryNode [id=979cf868-1c37-424a-9ad1-12db501f32ef, addrs=[0:0:0:0:0:0:0:1, 127.0.0.1, 172.31.16.213], sockAddrs=[/0:0:0:0:0:0:0:1:0, /127.0.0.1:0, /172.31.16.213:0], discPort=0, order=36, intOrder=24, lastExchangeTime=1512907805688, loc=false, ver=2.3.1#20171129-sha1:4b1ec0fe, isClient=true] [15:10:05,701][INFO][disco-event-worker-#61%statement_grid%][GridDiscoveryManager] Topology snapshot [ver=36, servers=7, clients=5, CPUs=128, heap=160.0GB] [15:10:05,702][INFO][exchange-worker-#62%statement_grid%][time] Started exchange init [topVer=AffinityTopologyVersion [topVer=36, minorTopVer=0], crd=false, evt=NODE_JOINED, evtNode=979cf868-1c37-424a-9ad1-12db501f32ef, customEvt=null, allowMerge=true] [15:10:05,702][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionsExchangeFuture] Finish exchange future [startVer=AffinityTopologyVersion [topVer=36, minorTopVer=0], resVer=AffinityTopologyVersion [topVer=36, minorTopVer=0], err=null] [15:10:05,702][INFO][exchange-worker-#62%statement_grid%][time] Finished exchange init [topVer=AffinityTopologyVersion [topVer=36, minorTopVer=0], crd=false] [15:10:05,703][INFO][exchange-worker-#62%statement_grid%][GridCachePartitionExchangeManager] Skipping rebalancing (nothing scheduled) [top=AffinityTopologyVersion [topVer=36, minorTopVer=0], evt=NODE_JOINED, node=979cf868-1c37-424a-9ad1-12db501f32ef] [15:10:08,706][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Cancelled rebalancing from all nodes [topology=AffinityTopologyVersion [topVer=35, minorTopVer=0]] [15:10:08,707][INFO][exchange-worker-#62%statement_grid%][GridCachePartitionExchangeManager] Rebalancing scheduled [order=[statementp]] [15:10:08,707][INFO][exchange-worker-#62%statement_grid%][GridCachePartitionExchangeManager] Rebalancing started [top=null, evt=NODE_JOINED, node=a8be3c14-9add-48c3-b099-3fd304cfdbf4] [15:10:08,707][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=2f6bde48-ffb5-4815-bd32-df4e57dc13e0, partitionsCount=18, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] [15:10:08,707][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=35d01141-4dce-47dd-adf6-a4f3b2bb9da9, partitionsCount=15, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] [15:10:08,708][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=b3a8be53-e61f-4023-a906-a265923837ba, partitionsCount=15, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] [15:10:08,708][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=f825cb4e-7dcc-405f-a40d-c1dc1a3ade5a, partitionsCount=12, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] [15:10:08,708][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=4ae1db91-8b88-4180-a84b-127a303959e9, partitionsCount=11, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] [15:10:08,708][INFO][exchange-worker-#62%statement_grid%][GridDhtPartitionDemander] Starting rebalancing [mode=ASYNC, fromNode=7c286481-7638-49e4-8c68-fa6aa65d8b76, partitionsCount=18, topology=AffinityTopologyVersion [topVer=36, minorTopVer=0], updateSeq=-1754630006] so in clusters with a big amount of data and the frequent client left/join events this means that a new server will never receive its partitions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
