Question on region server/data node restart

[Michael Dagaev]

Hi, all

     As I understand, I can stop a region server and a data node in a cluster
"semi-transparently" for clients, i. e. the requests handled  by the
region server
at that time will fail, but cluster will be working.

If I start the data node and region server  I do not have to do anything to make
them work.

Is it correct ?

Thank you for your cooperation,
M.
