A connection > exception may be thrown by the RPC layer(A IOException with "Connection > closed" message in this case). The RSProcedureDispatcher will regard is as an > un-retryable exception and pass it to UnassignProcedue.remoteCallFailed, > which will expire the RS. > Actually, the RS is very healthy, only the master is restarting. > I think we should deal with those kinds of connection exceptions in > RSProcedureDispatcher and retry the rpc call -- This message was sent by Atlassian JIRA (v7.6.3#76005)
