hi, 吴靖
I have got this error before. Please stop hbase on your cluster first. And
restart them with certain sequences: first regionserver on all nodes, then
hmaster.
Wish it helps.

it will happen.
Of course, the real question is how to get a secondary name node going

secondary name node? Or should we restart the name node first? Or is
there some other way for us to get right with our cluster?
Thanks,
Charlie
