hi all,

We are testing the zkfc for name node HA. And I see the design of the =
zkfc,
there is a monitor thread which will monitor the healthy of name node =
and the design
mention that the RPC timeout option, i want to know how to configure =
this option and=20
if the option is used just used when the name node is freezed or too =
busy to handle the monitor request?=20
if this option is usefull when the name node process is crashed?

Any idea will be appreciated!=
