步骤3：删除被替换节点的feventlog。
$ gcadmin rmfeventlog 172.168.83.13
after rmfeventlog 172.168.83.13, fevent log will be removed, must run gcadmin
replacenodes to replace this node.
you realy want to remove node 172.168.83.13 fevent log(yes or no)?
yes
delete ddl event log on node 172.168.83.13 start
delete ddl event log on node 172.168.83.13 end
delete dml event log on node 172.168.83.13 start
delete dml event log on node 172.168.83.13 end
delete dml storage event log on node 172.168.83.13 start
delete dml storage event log on node 172.168.83.13 end
