Start HBase cluster with more than one regionserver. 2. Create a table with precreated regions. (lets say 15 regions) 3. Make sure the regions are well balanced. 4. Restart all the Regionservers process at once across the cluster, except HMaster process 5. After restarting the Regionservers, successfully will connect to the HMaster. *Bug:* But no regions are assigning back to the Regionservers. *Master log shows as follows:* {noformat} 2015-03-26 15:05:36,201 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStates: Transition {8f62e819b356736053e06240f7f7c6fd state=OFFLINE, ts=1427362536106, server=VM2,16040,1427362242602} to {8f62e819b356736053e06240f7f7c6fd state=PENDING_OPEN, ts=1427362536201, server=VM1,16040,1427362531818} 2015-03-26 15:05:36,202 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStateStore: Updating row t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd. with state=PENDING_OPEN&sn=VM1,16040,1427362531818 2015-03-26 15:05:36,244 DEBUG [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Force region state offline {8f62e819b356736053e06240f7f7c6fd state=PENDING_OPEN, ts=1427362536201, server=VM1,16040,1427362531818} 2015-03-26 15:05:36,244 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStates: Transition {8f62e819b356736053e06240f7f7c6fd state=PENDING_OPEN, ts=1427362536201, server=VM1,16040,1427362531818} to {8f62e819b356736053e06240f7f7c6fd state=PENDING_CLOSE, ts=1427362536244, server=VM1,16040,1427362531818} 2015-03-26 15:05:36,244 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStateStore: Updating row t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd. with state=PENDING_CLOSE 2015-03-26 15:05:36,248 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=1 of 10 2015-03-26 15:05:36,248 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=2 of 10 2015-03-26 15:05:36,249 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=3 of 10 2015-03-26 15:05:36,249 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=4 of 10 2015-03-26 15:05:36,249 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=5 of 10 2015-03-26 15:05:36,250 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=6 of 10 2015-03-26 15:05:36,250 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=7 of 10 2015-03-26 15:05:36,250 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=8 of 10 2015-03-26 15:05:36,251 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=9 of 10 2015-03-26 15:05:36,251 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.AssignmentManager: Server VM1,16040,1427362531818 returned java.nio.channels.ClosedChannelException for t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd., try=10 of 10 2015-03-26 15:05:36,251 WARN [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStates: Failed to open/close 8f62e819b356736053e06240f7f7c6fd on VM1,16040,1427362531818, set to FAILED_CLOSE 2015-03-26 15:05:36,251 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStates: Transition {8f62e819b356736053e06240f7f7c6fd state=PENDING_CLOSE, ts=1427362536244, server=VM1,16040,1427362531818} to {8f62e819b356736053e06240f7f7c6fd state=FAILED_CLOSE, ts=1427362536251, server=VM1,16040,1427362531818} 2015-03-26 15:05:36,251 INFO [VM2,16020,1427362216887-GeneralBulkAssigner-0] master.RegionStateStore: Updating row t1,55555555,1427362431330.8f62e819b356736053e06240f7f7c6fd. with state=FAILED_CLOSE {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
