If RS holds a region which master think should be on > another RS, the Master will kill the RS. > But, the regionServerReport could be lagging(due to network or something), > which can't represent the current state of RegionServer. Besides, we will > call reportRegionStateTransition and try forever until it successfully > reported to master when online a region. We can count on > reportRegionStateTransition calls. > I have encountered cases that the regions are closed on the RS and > reportRegionStateTransition to master successfully. But later, a lagging > regionServerReport tells the master the region is online on the RS(Which is > not at the moment, this call may generated some time ago and delayed by > network somehow), the the master think the region should be on another RS, > and kill the RS, which should not be. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
